Thats his site and bio.

I was in London in '76 after the IOM TT and went to check out Dave Degens Dresda Autos, walked in, nobody there. Said hello, looked in the back, nobody. Looked around for a while, stood out front, never saw anybody there, doors wide open! I was there about 1/2 hour.
I did have a Dresa box section swingarm on my NorBSA. Good quality stuff, brazed Reynolds 531, tapered rollers. That came years later by mail order (before online ordering, we had to phone far away and send letters that took a long time, then wait a long time for parts to arrive).

Degens is THE man for designing and building Tritons. I spent dozens of hours studying photos of his Tritons while building mine.
