Uli - the reason i ask you to make a list of stampings found on all the parts of your vin: then we canb use your vin as the basis of comparison to all other stampings we find on our vins.
to know what we talk about what we think, consistency must be established. if we have the stampings on each part on your bike, then we can compare and contrast stampings we find on parts of other parts from other vins.
if we do not begin identifying every stamped number, letter and character found on parts we have nothing to contrast or compare so we can establish a pattern of consistency.
Uli - i am sure you understand the importance of this and why we need you to find and photograph every stamping on all of your parts. You can make a very important contribution.
