I just measured the opening on this holder and it is closer to 6x8 than 6x9. The horseman holder that I had (sold yesterday) is a true 6x9. Graflex called this holder a RH8. I shot a lot of 6x7 (pentax 67) and liked the size of this negative in that I could use. a 6x7 negative carrier in most cases. Framing with a RFH is not as precise as an SLR like a Nikon's 100% viewfinder.

Stone, I take it that you no longer shoot 35 mm as that is a 2:3 image ratio like 6x9.

Thanks all for the lovely bump ;-) and this holder is still for sale!
