TOPIC: Unknown 17' boat?

Any ideas as to who made this? It was a freebie of CL.
It's close to a few Aerocraft York models but its not a dead on match. The dash and bow area differ slightly.
It measures 17' 1" long with an 82" beam, the steering appears to have originally been mounted in the center via rope and pulley, the keel ends 2/3rds of the way back, and the squared off bow has two 4" wide deep grooves. The deck is all glass, no wood, the seats are attached with well nuts much like an older MFG. The transom is 2 1/4" thick and made from 2 layers of 1" cedar plywood capped with an extruded panel to match the splashwell cut out.
The title doesn't state a make and calls it a 1955 ARR. The title and HIN was asigned back in 1974 and it's not been used since the early 1980's.
Any ideas? Maybe just a different year Aerocraft or something completely different?
