hi charles:

what a great camera!
if i didn't already have a graflex 3A autographic and a kodak 3a folder
i would buy this in a heartbeat !

with the roll back on you can trim barely a few mm of paper off the long edge of 5x7 paper
and expose a beautiful full frame 3.25x5.50 image on it. i do it all the time with my graflex

good luck with your sale, it is worth way-more than your asking price seeing the
accessory / plate back is as rare as hen's teeth !
