pre unit ocd

Hi, I bought a box of parts which included a pre-unit frame. The serial numbers are gone but I have the part numbers. the front portion is F3537, the rear portion is F3563 and the rear swing arm is F3539. The 1954 parts book shows F3638, F3635, and F3646 respectively. Can anyone tell me what model and year this would be from?

There isn't much to see on the frame. It is a late 53-56'ish swing arm type frame. What I would like to know is which year and what model it would be.

Swinging Arm frame came out with the 1955 model year (actually late 54). There should be an ID stamped on the left side of the headstock which would identify it as to model and year.
