I took Brian's advise and bought a Stanley No. 53. Two, actually. The first is a "pre-sweetheart" era that a previous owner modified by rounding off the rear of the sole. It was very nicely done, and should be able to get into some fairly tight inside curves. The second one is still on its way, but looks to be in good condition except for the iron, which is a bit pitted. I know replacement slotted irons are available, but does anyone know if a 151-type iron will fit in a 53? The selection is a lot better if it would work. If not, can anyone verify that a Kunz iron will fit?
Also, when I got the first shave in the mail, I was surprised that the extent of the throat adjustment was only about 1/16". Does that sound right to any of you other 53 owners? I would also also think that a thicker iron, like a Hock, would limit this even more.
