Mahogany is a pretty soft wood and I would wager that the "breadboards" at the top and bottom are of a harder wood to prevent them from wearing out quickly. I know that many of the old studio cameras used Mahogany for the body, and Cherry for the base and anywhere moving parts meet

Thanks Sandford,

Guess most of us ‘woodshoppers’ would consider mahogany as a hard wood, and I’m pretty sure most of the British mahogany made camera’s had breadboards made of the same wood as this Perken camera: matching the wood of the middle board. However to prevent warping, the breadboards have their grain direction perpendicular to the grain direction of the middle board. Further it’s important that the splines are not cut along the grain...

I was shooting a nice PS&R lens today on my 8x10. It is a 10x12 "Optimus" RR of about 400mm.

Thanks for passing by Walden and giving info on your PS&R lens. In the meantime I got two of these nice lenses, one for fullplate - about 250mm and one for half plate.
Would love to see your results.
