that's cool. You can see clearly how that horn would eventually become the Miraphone 186.
Yep, I'm Mark

comment on one remark and a small part of the main picture:
Though obviously replaced - and the last curve into the #1 casing not being as sharp as the original - that's not all that bad of a mouthpipe bending job, particularly since the person who did it probably did it "free-handed", in additional to the fact that nickel silver is considerably stiffer metal than yellow brass. Further, the large end of a tuba mouthpipe (regardless of the material) is much more difficult to bend "nicely" than is the rest of a tuba mouthpipe.
That inside curve (physics/mechanics) is going to be considerably thicker than the outside curve, and the ugliness/ruts could likely be filed and sanded away- still leaving plenty of material - possibly as much as on the outside curve.
Rotary instruments that old - with original rotors that are not rebuilt nor replaced, YET "good" - are rare.
I have such an instrument here (something special, and intentionally being vague to avoid private messages) with astonishingly NOT-worn rotors (age: approx. 160). I would love to conclude its repair and offer it for sale (special market) but I've accepted a few more repair jobs than I should have (being that times have been quite uncertain).
(Assuming only approx. .5mm thick sheet metal) instruments that thin and that large - which are free of patches - are also rare.
