Hi. I’m looking for parts, information or anyone who might be able to guide me on the restoration of a flying squirrel. 

even determine the year and model is a challenge   The frame is 3864m   Engine fy12/35 RB     I have been in touch with Scott owners club in UK and they tell me that frame already exists in London and that engine number is not correct.    Well they are right here in Ontario!!   I have proof.   

any help would be appreciated

The engine prefix FY was first used on late 1926-early 1927 Flying Squirrel 596cc engines with 74.6mm bore and 68.25mm stroke. From such records as I have the "FY" was used up to and including year 1932- 1933 "Flying Squirrel" models.

The picture of the frame #  is of "3894 M"and according to the records published in the VMCC Register of  Machines in 1991 this could be a Scott frame from the year 1934. The suffix "m" (usually a "M") seems to occur on some of the bikes on record but not on all and I have no idea as to what it signifies.

I note on the engine number that the "RB" stamping appears to be done with a diferent stamping set than the one used do the FY 12 (slash) 35 so it may not be of "factory origin". The reverse slash between the "12" and the "35" is also not a marking indicated on any of the information that I have. Could the "RB" possibly stand for "ReBuilt"????

Scott "FY" series engine numbers seem to be FY followed by a 4 digit number, which is sometimes followed by an "M" or "A".

There were, apparently, some "Late short stroke engines" with "FZ  (498cc) or "FY"(596cc) coding produced and I wonder, without any evidence if the engine code of FY 12 slash 35 is original and "35" is 1935. Later Scott codings have "DPY" (detachable head 596cc engine)
