For your auction bidding consideration, a fairly uncommon antique camera accessory, here's a ground glass focusing back, made by the Eastman Kodak Company probably around 1905, for shooting 3 1/4 x 4 1/4 inch glass plate or cut sheet film exposures with a classic No. 3 Folding Pocket Kodak camera. Please look at all the pics because they are part of the description. It's in excellent condition, with supple external leather covering, intact door latches, intact pop-up viewing hood, and the complete intact original ground glass focusing screen. This is a true open auction, no reserve, starting at only 99 cents, and shipping within the United States is a fixed fee of only $5. International buyers are required to pay the actual cost of shipping as calculated by eBay for this 15 ounce parcel.
