A Hotchkiss Case

[Shell Shifter]

6" tall. About 75mm caliber +/-
All brass case.
Thoughts?

What is the rim diameter? If you want a positive ID you need to give dimensions that are more precise.

 

[Shell Shifter]

Rim=3.37"
Dia at opening =2.98"

I checked my references but I have nothing coming close nor do I remember ever seeing such a shell case.

Basic Hotchkiss "made-up" case, probably from the late-1800s. Probably US 12pdr. Used a lot for naval ordnance.
This Patent probably applies to the steel case you were asking about as well.

It's short so unlikely naval, look for a mountian gun of some sort that's under 3" bore.

 

[Alpini]

The US 3-inch field gun case is not far from your measurements: 2.96" x 6.20" rim 3.46"

There was also a US Navy breech loading 12pdr Landing Gun around this time. It used a separate case, but I have no dimensions for the case.
