The Triton cap tube is identical to the Jr Gent 2 cap tube, but the body tube is (IMO) significantly shorter (something like 2.09" for the Jr Gent vs 1.85 for the Triton) In case you're looking for a symbol of that difference, the Triton body and cap tubes are almost exactly the same length, so if you have a set of Jr Gent 2 tubes, the body tube for the Triton would be the same diameter as the Jr Gent body, but the same length as the cap.
The difference is significant enough that I had a Jeff Powell scrolled blank I was planning on making in a Triton, but I wasn't going to be able to keep all of the design within the shorter tube size to my liking...
