Glassless for both my 23C II and MXT 4x5 - already have multiple formats for each (35mm - 6x9 for the 23 and 35mm - 4x5 for the45).
I have wondered if glass would help when attempting to print image at the end of a strip (have you ever noticed if you trim to close, that is the one you want to print? or is that just my dumb luck)
