Mmm... Let me see. I think I happen to have one of those. Oh here it is...
I know, I know Pete, you probably didn't know it existed. And to be fair, I don't have an isolated shot of
the pant guard. I do have as many l
arge, shots of a Regent as you might want to see, to properly do the comparison. The bell to body brace & the key guards, are the 2 features that immediately tell me that the horn in your gallery are a Regent stencil.
There are an obvious differences as well. The neck brace is a throwback to an earlier model.
Tenor 4114 has the same neck brace.
BTW, after spending nearly a year playing this Regent, I can tell you that it is a very good horn. Its main problem is that it is still original in all aspects, and needs an overhaul. (Corks, felts, & yes, even pads.) It was built as an upper-level intermediate model sax, and can keep up quite handily with my pro horns in the area of intonation, tone, and to some degree ergos. (Obviously a Mark VI will beat it in the ergo dep't.) It's main issue is that is not 100% even in scale, but, since it needs an overhaul, it's not possible to say with 100% certainty that is related to the fact that the horn is still how it left the factory in 1963--although I suspect it is. BTW, I am likely making the evenness of scale sounding worse than it really is. I am just extremely picky. There are only a couple of notes affected, which is why I believe it to be a (lack of) maintenance issue.
