Hi there Vespa enthusiasts.
The chassis number is a VLB1T - a 1970 Sprint 150 but the Engine number is simply as per the attached screenshot - no series prefix. I don't think it is safe to assume that it is a VLB1T engine - If I am looking to identify this engine so I can replace one of the Fly-side needle roller bearings that was almost completely mashed when I dis-assembled - any idea on how I can go about identifying the replacement bearing if I don't find the prefix VLB1T when searching the engine numbers on http://www.scooterhelp.com/serial/ves.motor.serial.numbers.html
