While these aren't common tools, I do wonder about their application: most planes are best on work that runs through, and a lot of chamfers on traditional work are not through chamfers, but stop as they approach joints. The Stanley 65 spokeshave seems to have been designed for such chamfers, but I'm wondering if the cabinetmaker used the spokeshave to start the work, then transitioned to the 72 for the bulk of the run - ?
I ask partly because I bought myself a Stanley 65 spokeshave some time back (another tool that's languished as I try to get the refurbishing of the house done - which will take forever at this rate!).
