It's the fairbanks Morse set-up that was specifically made for Rupp bikes. It's a little smaller, but looks mostly the same.

This one is a 5/8 version (non-Rupp).

He just needs the backplate portion. The problem is the backplate is always the piece that gets stuck. It's made of aluminum, so if you put a puller on it, it just cracks, or breaks. They're very fragile.

If you can't find a 3/4" version, you can always put a Comet Symmetrical primary on it. They go for about $60 on Ebay, or about $50 for the knockoffs, that seem to work just as well.
