Rossin Quattro seat tube question.

I have a Rossin Quattro frame that I am going to refinish. This frame has a set of numbers on the upper end of the seat tube on the non-drive side
"WMR 20685 D" what does this signify? It doesn't seem like a serial number. The only other number on it is the frame size "58" on the underside of the B/B. This is my 3rd Rossin and the others did not have anything like this. Anyone know what it means?

Looks very similar to the frame numbers used in some european countries. First 3 letters represent the factory or importer, numbers = the serial number and the letter indicates the year of production. In this case D = 1988. Is that about the year your frame was from?

I don't know the year for sure. There is a hand written decal on the chainstay that says 1985. I can only assume it was placed after the frame was stripped/sandblasted.

I think my reply from Friday didn't post for some reason. But anyway...I'd dare say it was imported to Denmark in 1988. W=Import, MR=Ritter Sport, D=1988. Could very well have been produced in 1985 but not imported until later.

Agreed, that serailization is consistent with a bicycle intended for the Danish market and would indicate 1988.

Interesting, thankyou.
The guy i got it from stated he got it from the factory. I cant confirm that but he does have a excesivly large Rossin supply.
