Scooterotica

Evening all,
My mates got a series one framebreather frame which he intends to get registered and back on the road.
Question is, the frame number is stamped on the frame underneath where the air box goes and not in the normal position.
Anyone know if this is normal ?
Can`t make out the whole IGM/frame number without a bit of paint stripping but what i can see it looks pretty original.
Cheers.

Thats the correct place for the frame number, it moved backwards for later models

id like to see some before and build pics

Cheers CPH, you learn something new every day.
Ricspeed, you may be waiting for a while he`s had it in his living room for a year just gathering dust.

btw the frame i picked up today has the number there also
