Indian GP 150 Frame number......

A mate is just starting on a GP 150 project, its an Indian import..
The frame number looks like 102515
Can any of you roughly date it from this, I cant quite tell if that's the full VIN number, the stamping looks terrible... although it doesn't look dodgy (ringer), just factory bad.. hope this makes sense...!!!!
thanks in advance for any help..
