Thank you for that image Les,....In the attachment, I rotated it a bit ,so as to try to get my bearings on it's position. I drew a red arrow to a point of interest to me, ..is that a rust spot , a rivet hole , other??
Monty, I deal with a lot of vintage autos and motorcycles from the 30's and many of them have rolled edges on the fenders/hoods, etc,... that type of fabrication was pretty common in that era to strengthen parts, at least regarding those vehicles anyway.
