I may have some new glass. Bought some 6-digit and 7-digit glass 6-8 years ago. Paid enough for it, would probably need $55 + shipping. There's probably a cheaper option somewhere out there for you. Seems going rate is a bit more than that. LMK though if you're interested & I'll head to the basement and see if I have the 7-digit in the configuration you need. Do you need it without the bubble/nipple on the back? Sometimes pcbs don't have the hole to allow for that so the glass has to be flat on the back.

Looks like I just 3x of the ones with the bubbles out the back, NOS.

I always hated that.. the flat versions are probably fairly hard to track down.
