Fred et,al. I'm very much appreciating all the input. Here are some photos of said beast. Do any of you see anything funny about it? If you want some more photos, I'm literally 50' from it as I sit.

I just ask because, first, been there, done that (tuned to 440 not knowing it was built to 415); and second, Tyre would have a well-scaled instrument, unlikely to break strings more than occasionally. Changing the gauges isn't likely to solve the problem. But checking some lengths and scaling is a good starting point, to see how it stacks up. There isn't a whole lot of variation, except when you come to how much the instrument is foreshortened, and so where the brass starts and how thick it gets. That is, the high treble is pretty well all in the same ball park, for any instrument. Changing gauges will change tension, and raising gauges could cause structural issues (and change the timbre). But, as a very long-winded thread a while back demonstrated/illuminated, the notion that thinner wire is less likely to break for a given length and pitch is not very accurate. If there are differences, they are small and unpredictable.
