Looking for pics of bodies with 1/4" top round over and 3/8" or 1/2" back round over. Has anybody any experience with this?

I'm making a J right now. I started with a quarter round and it wasn't enough. I'm going to go with the 3/8 in the next couple days.

I don't have the Fender specs, but if I had to guess, the '51 P was 1/4. Any of the modern Fenders are 3/8.

If that helps.
