Could this be a Seacraft?

[spareparts]

I think its the 21, it was the only one with a sweeping shear line, they were rare as only a hand full were built. Theres been a couple restored on classicseacraft.com To me its the best looking one they built. They were the early racing models. There's a bunch of history about them on the site. great boat to restore, may be worth some money as it is
