Here's a truly beautifully made 19th Century lens board.  It measures 11x11in, so it's likely for some 11x14 or 16x20in studio camera.  The lip is 1.4in thick, and lens opening is only 3in, so you can easily enlarge that opening to fit any number of large Petzval lenses on this board. The board could use a little cleaning, but it's in perfect working shape and has survived the past 140 or so years wonderfully. 

Feel free to ask question if you have them.
 I’m a photographer myself, and have been buying and selling equipment on here for over 20 years now. I always do my best to describe the items as accurately as I can. Take a close look at the pictures, I try to show all possible flaws there, and so in real life my items look better than on here.
I'm putting slightly higher prices on International Shipping, because I never know how much exactly it will cost to ship the items.   Once I ship your item, if you overpaid for shipping by more than $10 or so, I'll immediately send you refund on shipping cost.  Of course I also combine shipping, and refund the extra shipping cost on that as well. 
Good luck bidding.
