A serial number is stamped on the top starboard side of the exterior of the stern (where you would expect a HIN on a new boat) that begins with "DD"
The windshield is marked Taylor Made; there is a second set of screw holes closer to the cockpit, so it may be a replacement for an original that was smaller. It also came with a Taylor Made bimini, and there is a (broken) Taylor Made "Chart Liter" in the dash, and it came with an Airguide speedometer that had water inside the crystal.
There's a small plaque on the (wood) dash that says "Doc" Chauvin, Worcester Ma (very close to where I picked up the boat), who I assume was the dealer/outfitter.
I do have a catalog. I'll scan it and send it to you.
I think we have the same boat. A 1959 SeaMist. Yours with steering and windshield was $695.00 new. someone gutted all of the front bow metal on mine...I have a 25hp Gale Buccaneer on mine
(I have a price schedule from then also)
Congratulations on identifying your boat. Original literature is invaluable when seeking to identify or restore a vintage boat. If you have scans of your catalog and would like to share them with other owners, we can add them to the FiberGlassics Classic Boat Library for all to enjoy.
