Phil Thomas has the 8255 cowl that also fits some of the 7931 hulls, and Don Mckay has the 7931 Circus/ Squire cowling. Joe Stieman is working on 80 bud humpback cowling right now.
Jeff Snell I know has the modern "T6" style cowl, and the 7474 Olympia Beer style cowling. I have wood frames that make the 73-74 'ish Pay Pak, '76 'ish Atlas, and Miss Madison cowling as well.
