Tube ID Help?

I dunno, they say Yugoslavia on them, and it's about half rubbed off, but I'm not sure. They don't have the pointy pins or saucer getters. The getters are a simple ring that is all one piece with the splash shield. They seem to be pretty fat for whatever that's worth. I'm hoping maybe EI, but I can't figure them out, and I know there were a lot of knock off chinese jobs out there (don't ask me how I know that).

I've got a couple of those that were in a motorola console. They actually sound pretty good. Mine had all of the lettering worn off them, tho.

Yeah, they do sound pretty good, I was just trying to figure out who made them?
