92g cube identification

[Dryanimtt]

Wondering if anyone can help me identify who makes this cube. Guy I bought it from said marineland but in not sure that's accurate. And it's of rather odd construction to me. My main concern is, is it supposed to have a top rim because it has a bottom rim.

I doubt it's a marine land, if it is it's a pretty old model... looks more like a custom build. Black trim on the bottom and rimless on the top is pretty standard with a lot of tank makers. I wouldn't be concerned about it not having a top brace. How thick is the glass??

Glass is 1/2" thick
