In acquiring Auto-Strops I've managed to accumulate a fair quantity of NOS Valet blades. I examine each one under a microscope before attempting to use it and about 1 of every 3 or 4 blades still has an acceptable edge, despite the fact that they all look fine to the naked eye.
Even the best ones still require a good stropping before use, so unless you have the strop that originally came with your razor (and it is in usable condition) I wouldn't try to use the NOS blades.
Even a good NOS blade thoroughly stropped will not produce a shave as good as the Feather FHS blade.
