Imperial? Other modern?

All the other marbles in a large lot were definitely American and 40/50's ish. I'm guessing these are rogues, unless I'm missing something...

Thanks!

 

Size from 5/8" to fractionally larger - 11/16" ish

That's tough.  Maybe they're an early version of what came to be known as Imperials?

But I guess they could also be flat-out Masters based on the lot being mostly American. 

I guess the biggest thing which makes them seem Imperial is finding such a number of them together.

Thanks - That's out of just over 300 mibs - there are about 30 brushed transparent Masters in the lot, and the size is good for Master, but the brushwork on the transparent Masters is typically slightly 'crude'. These don't have the crude patch the transparents normally have, nor the depth of glass patch that Meteors have.
