I'm going out on a limb here, but I think the Baron is a T/B exclusive product based on the Jr Gent? I can tell you from experience that the bushings are NOT the same! The difference is about 0.5mm, but it is there nonetheless.
Having made both there is a definite improvement in quality in the Baron, although to be fair I've only used the titanium-plated barons so the difference might be related to the finish. The other difference is that while the Jr Gent has a gold/silver ring sandwiched into the cap band (in between the opposite plating) the Baron has a black one. Ditto for the finial on the cap: baron = black, Je Gent = gold/silver.
