Help with frame size

[Jon Possom]

I've checked out the serial number info but still cant figure out if the frame size is stated within the serial number. Any help would be great THX

Believe that's a medium. Measure the wheelbase with someone holding the fork straight. MD wheelbase was 41.1", LG was 42.1".

I don't have any mountain bikes of this vintage, but the road bikes in that era generally have the size in cm stamped in the BB shell. Guessing that the MD in your frame code is the size. If anyone has anexample of a SM, LG, etc. frame code on a mountain frame it would be nice to see.
