So, I've been a happy costumer of the Bags cases so far and had one of those for many years:

I often have to carry different trombones due to different styles that I need to cover. The Bags case allowed me to take my Jazz horn, but also with some adjustments of the inner parts a Conn 88H or even a Back 36 open wrap.

Unfortunately everywhere I asked about the delivery for those cases it is either not possible anymore or takes a year (my old one has really worn off after excessive usage).

Does anyone have a good alternative for a hard case (no gigbag) that might be as versatile as I described?

Marcus Bonna and Protec iPac come to mind as hard cases that have "innards" that can be arranged to suit the horn.

I use an Eastman case for small and medium bores. I think it also fits an 88h. It has had Urbie 4501, 48h, Olds Recording, Yamaha 455, Conn 78h, 79h, 8h, 88h. It's a usable case.

I used to have a Eastman, The older ones before the black interiors. Wish I hadn't sold mine as I didn't realize they would be so hard to find.
