I can't thank @twhite enough for help with rescuing the famex by making a new cap for it. Normally I wouldn't even bother but this razor just grabs your attention the way it is designed from the form to the function. If it holds true to other French razors I've used one efficient but aggressive s.o.b. of a shaver. The original cap assuming they mixed famex base plates with SOS caps was broken in pieces. The new cap should be even better than the original since twhite made it out of brass while the SOS one was some sort of zinc or pot metal. Some before it goes out to be re-plated pictures will be forthcoming once it arrives along with a few shaves.
