I've got a wooden one with extension rail and gridded/clipped ground glass (uninstalled at the moment). Not sure of a lens board, but they are easy to get from the guy on Ebay for less than $10 anyway. Rubberized sort of bellows, light tight, gathering dust in the closet... $65 shipped in CONUS? I think the ground glass cost me $25 and it's never even been installed yet. Cheers, Richard
