Can you help ID this old Bach case?

[BandTeacher]

Hi all! I'm a newbie here.

I recently inherited a bunch of stuff from my old trumpet teacher. One of the items is this old Bach case. Just from looking at it, I'm going to assume its an Old Mt. Vernon double case. I'm hoping someone else can give some other pertinent info, like maybe vintage, etc.

Here is a shot of the case


Here is a closer shot of the metal plate on the top. The same plate is inside the lid


Here it is open. The horns sort of lay flat, not vertically like on the double cases I've seen and owned.


And the surfaces the horns lay on hinge upwards, and there are mouthpiece notches underneath


So can anyone add anything to what I've deduced? The case doesn't match any of the horns I inherited. There were 4 Bachs, but all Elkhart horns. But he had lots of multiple cases, so I'm sure maybe this was from a horn he sold or traded off earlier in his career.

Looks like a Mt. Vernon or early Elkhart double case. I've seen a few in the past. This was a way to fit two trumpets inside the standard case. I'd expect it as a way to cut costs and avoid having two different shells.
