Pretty cool, Martin Perry body maybe. The cowl is 30-E31, and is still considered a roadster cowl, that Ford offered converted for use with body by others. It is considered the roadster cowl, because it has provisions for doors. If you removed the top gas tank sheet metal piece, one could add ram horns and use it on a roadster. It wasn't until later in 31 that ford produced the true commercial cowl with no provision for doors and was flat flanged at the back to mount against a body by others. You will notice in certain pictures the cowl doesn't fit flat to the body.
