Kris, You have a beaut of a boat there. I'm assuming its strip planked and has no 'cloth and resin on it. Canvas covered, maybe? I'm sure you looked it over real well - sometimes there will be a brass tag or sticker / decal up under the deck, inside on the transom, backside of a rib or even under a chock (Penn-Yan did that on their smaller boats). Where are you located and do you know if the boat was locally built? My guess would be Minnesota / Wisconsin / Michigan and maybe even New York (Thompson built that style) No markings of any kind may mean it was a home-built or a kit offered from a company. Check with the previous owner and follow up any leads as to where and when it was used. Anyway, let us know if you find out any info on it. You planning on restoring it? Let me know if you need any help, I've done a couple like it. - Jim B
