As far as I can tell, this is an original (factory) board. I haven't seen any knockoffs that have both the inner and outer boards, as well as the linkage for shutter release.
Ian, you are correct that Heavystar sells new boards for 3 for $39 (also 1 for $16). I didn't see those because I did my search for "graflex" not "graphic".
Brian, thanks for the info on this board. The only holes that extend though the inner board are the flash holes (and covered up with tape).
So I suppose if you want a basic board, this one is overpriced and I apologize. I suggest you follow Ian's lead and buy on eBay (Item number: 200451992448). If you want a Super Graphic board, PM me.
