This instrument on Dillon's site has me thinking again, as I've mentioned before, that it seems like every one of these is nearly a one-off. Each one is wrapped a little differently, sometimes very subtly. I would love to know what was behind this phenomenon.

I was just comparing the picture of this one to a picture of one I used to own, because I thought at first that this was my old horn (being offered for sale at a stupendous profit over what I sold it for).

But it isn't the same horn, the wrap is very slightly different. The only ones I've known of that were as nearly alike, and yet as subtly different, as this one and my old horn had sequential serial numbers.

Were these tubas made before or after Conn introduced hydraulic bending of bows?

If before, slight differencesuv in bow diameters may have been hard to avoid, especially with the larger bows.

Yes, I can do that after while.

They fall into two big groups: those with the main tuning slide in the lead pipe, and those with it after the valves with the lead pipe going straight into 1. Most (all?) of those in the first group seem to have been made before the advent of model numbers, while a few of the second group do also, while most were made afterward.

I can put up some pictures of several examples of both after while. Gotta get back to work at the moment...
