I Love microskiff.com!
Yeah, you're correct about the Wedding Cake in 1967. I was reading something else at the same time and 1962 came up.I'm sure it was due to mass production & the availability of the Medalist. I think Pflueger got a patent on the Medalist in 1930. Lefty was always a big fan of doing more with less and convincing people to spend as little as possible to get into the game. I remember seeing a couple of those old customized Medalists at the Big Pine Flea Market back in the 1980s.
I think Fin-Nor came out with the Wedding Cake in 1967 and then soon after, Capt. Mac introduced the Seamaster.
I like vintage gear and have a couple old Medalists from the early-60s but I wouldn't try to tackle anything bigger than lower-slot reds with it.
