Elgin Thin Thin White Weave Dial

I’d love to know the case number on this one, but if is a front loader, I can’t get the movement to drop.  If the back is supposed to pop off, I can’t get enough force on it to move it.

Anyway, it has a cool white weave dial that has just a bit of patina on it.  I relumed the dots and hands.  Thanks to Stryfox for the case number 6850 and Diveboy’s great Thin Thin database, it seems this is a Thin Thin C.  And the back is supposed to pop off, hmmm.
