Greetings,
I've done some research on this, mainly thanks to this very helpful link:

Mine has no badge, but according to the lug style and the mount, I believe it to be a Kent. I found this paragraph from the link above particularly helpful:
During the 1950’s and 60’s, Kent snare drums and tom toms were constructed of two-plys of maple, providing a very thin and resonant shell, similar to Gretsch drums of the same period. Often, actual production dates were stamped inside the drum shells. Bass drums were of six- ply maple construction. These maple shell drums varied in construction quality. Some were beautifully finished inside, with true bearing edges, while other drum shells were crudely assembled, with dark brown glue smeared on the inside and virtually no bearing edges. It is common to see lugs and strainers attached crookedly as well. No two Kent drums were ever alike!
Based on that, I would say the wood interior on mine could fit the description of "crudely assembled with dark brown glue smeared on the inside and virtually no bearing edges". The wood doesn't really resemble maple, but it certainly doesn't look at all like Luan either. Also, compare the screws and "asterisk" washers on my drum to the "1950's maple shell tom tom" in the link above (4th photo from top). Also, it looks like the Japanese made Kent Shells had re-rings while the American ones did not.
What say you? The size is 9" x 13" (actual depth is 8.5"). I'm also enclosing a photo from the above link.
Thanks for your help,
