Graflex Crown Graphic 4x5 Ground Glass Replacement

[RussPhoto]

Hello everyone,
I just got my 4x5 Graflex Crown Graphic and had misfortune to broke ground glass. Fresnel screen is fine but ground glass is gone. I was trying to search on eBay replacement one but they don't have too many. Does anybody know where I can get original one? I appreciate your input and thank you in advance.

Put 'crown graphic ground glass' without the apostrophes in the search box in eBay and there will be at least two that are "drop in" for $18 and one "Genuine Graflex Speed/Crown/Super Graphic Ground Glass + grid" for $92.

You only need one.

I got this one from eBay. Thank you for your reply!
