Frame number on 10/12

#1

Post by WCC »

I saw this frame number on a military bike. It is the first such number I have seen on a flathead frame. Does anybody know what it means? Is it a military VIN?

Generally numbers stamped there are by the factory on a refurbished/repaired frame. There was also a stamped tag that went along with it. The number was used to identify what dealer it came from to make sure it went back to the same place.

However, some military agencies also stamped frames, notable the Canadian home models.

Here are some not so good pictures of a tag and the frame it went with, my 47FL.

And adding to that; there were countries where framenumbers were obligatory.
Even if the motor had a VIN and frames didn't have a number.
It is known that for example the dutch RDW (compairable with your DMV) stamped frames with a letter and number, so they could register it.
Many WLA's receive a framenumber that way, which is standard practice for framenumber-less motorcycles.
Since the late 1990's, most framenumber-less motorcycles received the VIN (stamped in the motor) as framenumber.

'R' could mean 'Rijswijk' where many vehicles are tested.
