When it comes to bell diameter and to bore through the valves Miraphone has an equivalent to the 151 Alexander. Only exactly that Miraphone happens to be oval:
Bb-Kaiser baritone, ovale style, 4 valves †
brass, nickel silver trimmings, spiral, CPU†† lacquered
Item 070056L07000
Key: Bb
Style: †ovale
Bell diameter: 310 mm
Bore of valve section: 15,5 mm
Number of valves: 4
Typ of valve section: 07000 nickel silver trimmings
Type of body : 07000 brass body
Material of mouthpipe: goldbrass
Finish: lacquered
Mouthpiece: BT06 lacquered
Sadly the Miraphone site is one of the html index types, so that I can not give an exact link. In a previous posting linked to below I have given an overview of the various bore configurations in the Miraphone Baritone line. Plus a working link to their site.
To confuse things furtherly:
I have met an elderly Danish amateur, who had an upright large Alexander Bariton (rotary euph/tenor tuba). That instrument has, what looks like 6 valve spatulas (4+2), but really there are 5 valves. The 6th spatula activates a trigger regulating the length of the tubing of the 5th valve. Sadly there was no chance to have a blow.
