The original Lambretta shield badge and script too are intact, and rarely seen these days in original form.
BHPian karlosdeville recently shared this with other enthusiasts:
The Lambretta Series 2 Li150 is probably the shape one thinks of immediately as the most recognisable Lambretta, though within the model run I believe many small changes were regularly introduced. I’m not expert on these, and I hope through this thread we can document with some backup what these changes were, and when they were introduced.
Here are factory photos, probably shot outside the API factory in Bhandup?

Surprisingly these models were rarely advertised in print – the older D and LD models and successor SIL models were advertised much more.
Naturally being targeted at lady riders, the owners manuals and other publications featured modern women astride the scooter. 
The scooter was no stranger to Bollywood too – an early model featured here in the film Parivar.
I assume that the model was launched around 1960, after the preceding Series 1 with fixed headlight. Do we have any known dates / data about the introduction of these models?
One point that seperated these bikes from their Vespa competition was the adoption of two tone colours – usually cream with red, blue, grey panels etc. The earliest bikes I’ve noticed had the nose cone and handle bar top in the same body colour (usually light grey / ivory), with just the side panels in contrasting paint. Later on this would spread to the nose cone, and finally the handle bar tops. The earlier bikes (perhaps between 1960 and 1962/63?) also sported side panel badges with a stylised Lambretta script carried over from the Series 1. At some point these were dropped, I assume in 1961/62. Later models also featured a pear shaped horn cast on the nose, replaceing the earlier rounded one. Speedometers would be Italian Innocenti units with a cream face, to be later replaced by localised ones by Yenkay with API branding, with greyish, or silver faces. I’m sure there were many variations. Later on came the Lamby 150 with flashes on the side panels and concelead panel handles, though that can be discussed another time.
There also seems to have been a healthy club movement in period, I have with me a very cool brass badge of the PLC or Poona Lambretta Club.
I also have this booklet and form from Madras and Trichy clubs.
The purpose of this particular thread aims to highlight the various rare original features of this scooter for reference. There are near to none surviving in this state of preservation. A barnfind or a preservation class vehicle is a term quite abused these days, but I’d like to think this one does qualify, even if a humble little scooter – an all original Lambretta Series 2 from the 60s in the same ownership for over 50 years.
Registered in July 1964, this scooter was originally owned by ‘The General Conference of the Seventh Day Adventist’, registered in Byculla. I assume it moved soon to the Poona campus in Salisbury Park. 8 years later in 1972 it was purchased from this Poona campus by a family friend who has owned it ever since – that’s an impressive 52 years! The gent maintained it himself with much love and care, and left India for Australia as early as 1983. He returned for a short while in 1986 when he used it again, and at the time he fondly recalls taking me for a ride on it when I was all of 18 months old! After that the bike was placed in careful storage indoors for decades. Only within the last few years was it relocated and parked in an open compound, though carefully tied up with multiple covers for protection. However that’s where most of the weathering and paint damage would have taken place, how I wish it hadn’t gone through that.
The scooter presents many unique features – the primary being the single colour throughout. In some old movies and photos I have noticed these single colour scooters, but never actually seen one in original paint. Its a light grey / cream shade, that has suffered from plenty of wear over the years. While it has cracked and flaked in many places, major rust has still not set in surprisingly.
We rolled the bike out of the compound for the first time in years, surprisingly the wheels were totally free and wheeling the bike out was effortless. The tyres were full, but of water! The scoot was parked in a charming old neighbourhood of Poona camp, the scooter blended right in. Note the heavy duty rexine bag ‘glovebox’ strapped on. A lovely period accessory that was once so common, now not to be seen. 
The original Italian headlight and ring is intact, with INNOCENTI lettering. 
The original Lambretta shield badge and script too are intact, and rarely seen these days in original form – Delhi made replicas are of course dime a dozen, and available in various qualities. Don’t miss the light grey leg shield and nose rubber beadings – unbelievable that the originals are still on the bike, I have never seen originals before. Great reference, though some of the pieces are brittle beyond use. 
An original Innocenti branded speedometer – this one is a real rarity since most bikes today have a Delhi made replica with a face in MPH and Veglia branding (the original is in kms and some other branding which I cannot read). 
The original kill switch is intact, as is the ignition switch with hinged cover. The original keys still operate perfectly. 
The handle bar mounted switchgear looks to be of poor local quality given the peeling chrome – perhaps this item was changed? Or already localised by 63 – any thoughts from the experts? The grips too seem to have been changed, I feel the originals were ivory plastic ribbed items, over to the experts to confirm. 
The original lock on the tool box, and again functioning with the original key.
A cool period accessory is this frame breather grille/vent, though dummy as there is no provision for ventilation. Were this ever factory fitted dummies or always an accessory?
Original taillight housing too is body coloured. Note the absolutely gorgeous period accessory number plate with vinyl highlights – silly items like this excite me the most 
Accessory theft lock on the spare wheel – again working with key. Because of this the disc that fits over the spare is removed, and luckily was safely preserved. 
On lifting the rubber matting, the original flooring was found to be surprisingly intact and rust free, and with the original ivory floor beadings. In good shape too!
Petrol flap is lockable (which I’m not sure, but may be an extra option). The tank was absolutely perfect and rust free on inspection. 
The set of 4 keys, well worn but working perfectly in each of the 4 locks. Indeed a treasure!
The spare wheel disc was carefully preserved along with some spares and the original tool roll and jack. The owner really took care of this bike over so many decades.
The original documents too are in perfect condition, including the plastic folder dated 1972, the year he bought the bike! A testimony to the stereotypical Parsee owned bike.
