Thanks, John. i'm sure he'll like it.
The original buckle was this type, which isn't available any more. In fact, this buckle may be the one off the original belt. The original was 2" wide but that's a bit much for today's belt loops. I have a couple of these old style buckles in 2" and 1-3/4". This new belt is 1-1/2" wide.
To get a double tine buckle, I robbed one off a second roller buckle.
