Estuche para instrumentos musicales 20x11x7 corneta trompeta? USMC Army Navy Marine Boy Scouts

My Inventory # Fiber Music 20x11x7 F/G E721 of 50. Appears to be a Bugle Case. Looks like there is a lot of bugle styles out there and I do not have any specifics on which fits in this case. Not an exact match for my WWII 1892 bugle but close enough.
