Modern Vespa

Is it a Douglas? Would that make any difference? Looks much like a legit stamp to me, or somebody was very talented long ago.

Should be VLB1T*XXXXX*, I don't see the T and the *

The star is there.

Sharp looking bike, but there are some concerns. Do you know its history?
VLB1T would be a Sprint which yours may be, it does look like this one from ScooterHelp here: https://www.scooterhelp.com/scooters/VLB.150sprint.html

I Like how this puzzle is put together here. Especialy the first import years from Italy to Indo, dan motors.
I inspected 2 Vespa 150 Sprint.
1969 1'st in parts with only, the 150cc Motor with new Piaggio emblem including brake pads and exhaust. A PX motor I would say. All the rest either no emblem or cheap after market parts.
Partly restored,packed up in boxes and signs of lost interest to deal with this pile. I call this a Frankenstein Vespa.
This one was registered and kept up to date.

1974 2nd complete, started, with maint records in WA and all the Indo paperworks and transfer stamps with Indo dan motor info, spare parts sticker on the hood. Strangely the Model ID and serial number was not on the left site. After checking the other side there it was, and matching the documents.
Research showed that serial number location changed officialy in 1970 for the Model Codes VLB 1, VNC 1 and VBC 1 models.

Few welds in the back, but fully operational with ugly paint work.

(Both the above Vespa frames when comparing to PX made in Germany Augsburg and Primavera from Motovespa in Spain, had quite thin gauge metal I found today)

Question 1: Are the Indo dan motor vespa chassies thinner gauge or is this normal for the eara overall?

Question 2: The Model Code and S/N sequence found was Letters and numbers VLB10.....Ahead of the serial number.
Are the Indo dan motor model numbers without a T and then continue with S/N?

The only other licenced importer I found with Model Code and missing T is Douglas Bristol UK. Their Model Code is Letters! VLBI...followed by the S/N

I guess his bike is a bodge
Hope he did not paid too much and his bike will never split into 2 1/2 vespas...
