Large Leather Canister Rock Island Arsenal - for Artillery Accessory?

[checkit]

Hello - I am listing this here as much of what I see from the Rock island Arsenal seems to be related to tanks & artillery. Large russet leather canister outside dimensions 12 1/4" tall x 6" diameter, stamped 15 5 455 R.I.A. with inspector initials. Any thoughts on this, fellows? Thanks in advance for any opinions you can render.

Your leather canister looks very much like

the ones used to store spotter scopes.

Thanks - I still have this, and have still been trying to figure out what it is.

That number is the Rock Island Arsenal drawing number. If you can locate a list of those numbers you may be able to tell what it is.
