I used to have a 7"x14" Leedy that looked almost exactly like those. It was a single ply Maple shell, almost 1/2" thick. It was from the 30's or 40's I guess, but it sounded pretty good, but the strainer sucked royally...so I gave it to one of my friends for Christmas. He left it in his car one day, and the heat (we're in Florida) caused the shell to crack!
I liked the Wooden 10"x14"'s, but man do I hate the metal ones. I had a chromed/steel Olympic 10"x14".
