1. B-flat (big fat sound - up-to-and-including "nuclear", wide applications, handy - size-wise - when bringing along auxiliary instruments.
2. C (can walk softly and/or carry a big stick - used for more orchestra concerts, though the B-flat has begun to "horn in")
3. E-flat (for all sit-dozen jazz band combos. fully chromatic, sounds like a big ol' B-flat tuba, but much less work and more facile)
4. F (for all of those tuba concerti that I play with "big 5" orchestras, annually...mostly, for brass quintet work and lighter orch. lit)
5. B-flat euphonium (for anything that's really absurdly screamin'-high, when anything else sounds too thick, and - being "large bore" - for covering bass trombone parts without struggling with a playing slide)
6. F cimbasso (for many - often: most - pieces played on "pops" concerts, for playing trombone quartets, for covering the rare "contrabass trombone" written part, and for playing Renaissance transcriptions with brass quintets, and - ok: whatever - playing "stuff Verdi wrote for a widely-debated instrument")
----------------
There are no makes/models - of any of these genre - that I would swap for any in the picture.
I continue to recognize how very lucky I am, to have access to this set of equipment.
Three were made in eastern Germany, one was make in the UK, and two were made from hodgepodges of parts: one from USA parts, and one from random parts.
Other not-shown instruments (valve trombone, English compensating baritone, kaiser bariton (rotary), (even a) smaller-bore (non-comp) euphonium, kaiser B-flat, sousaphone, Flugabone (bass trumpet), pocket trumpet) have been granted exemptions, for the time being, but some will (possibly/probably/eventually) disappear.
