Hello Mauro 88298 is one of 15000 bikes under contract S1048 (1943) and I calculate the tank number as C5122328. It's from a contract of solo's and shouldn't have the brazed on sidecar lugs?
Here's one from that contract. Ron
Hi, he was corrected, he has the attached supports of the sidecar frame, so he certainly was born as a single motorcycle and then the sidecar was added at a later time.
Thank you
