lot of 3 - 5x7 Glass for contact printing, negative carriers, etc.

Description

I've transitioned out of large format, so I'm selling the many parts and accessories I've collected.  I combine shipping; please check out my other auctions.
Three pieces of 5x7 glass for glass neg carriers.   As far as I can tell this is not anti-Newton ring.  All pieces are nicely finished with rounded corners and edges.  Dimensions 180.0 x 130.0 x 1.5 mm.  One pieces has crudely clipped corners.   Knowing where these came from, they were probably for use with Omega or Beseler glass neg carriers.
The rectangular pieces are in glassine envelopes, the one with clipped corners has the glassine taped to it.
