I'd like to sell some miscellaneous not-useful-to-me items I found lurking on a shelf, and this is one of them.
This 4"x4" wooden lens board has a 32.5mm mounting hole and three screw holes where a flange was mounted to it (it originally came to me with a small Alphax shutter attached). The overall board thickness is 1/4" with 1/4" rebates all around where the thickness is reduced to 1/8". There's a "C" stamped into the back. One edge is chamfered as you can see in my crappy out-of-focus cellphone photo. I can't use this - can you?
$15 shipped in the US. PayPal is OK.
