Cleaning out the garage today and finding many things like this where I ask myself, why not sell that. The extension bed is the early style. Good usable shape. Easy to see that the tripod block doesn't quite fit. I don't exactly know what it DOES fit. Anyone? The last image shows that it misses the 8X10 bed by about 1/4". Yes, the handsome Bausch and Lomb 10" Petzval seen holding them up is also available. Ask. Bed extension; $125. Hey, if you need it, you really need it. Tripod block; $75 You pay shipping. Talk to me.
