For Sale FS Extension rail for Korona 5 X 7 camera (99% sure)

I bought this hoping it would fit an old wooden camera I have but it will not do the job. Once having it in my hands and checking with friends it is almost certainly for a Korona 5 X 7 camera. Outer dimensions are 10 1/2 inches by a hair under 6 7/8 inches. Outer gear track spacing is 6 1/4 inches and gear track metal width is 4 mms. The outer side metal track centre is 3/8 inch from the top of the wood frame. The 2 metal alignment rods are centred 1 7/16 inches from the outer wooden edge and the screw lock bolt is centred. Extension rail is in good condition and rigid and square. If you need any other dimensions please let me know. Stamped on the wood is the number 98 or 86 so if your camera has this number you have found the original track.

$50.00US plus shipping.

Sold - thank you.
