Antique c1912 Valet Auto Strop Safety Razor Set with Stropper, made in New York, USA. Rare version, can't find another like it. All Brass components including Removable solid Ribbed & Knurled handle and spare razor holder, which is empty. Appears to be New Old Stock. Believed to be un-used. There is one razor installed in the head. Metal case is straight with good hinges and latch. Inside of metal case looks almost new. Leather strop looks good. No Manual. Cardboard Boxes show age, wear, & tears. Estate find. Item has not been cleaned. Weighs approximately a little less than 8 ounces, unpacked. Box measures approximately 4" long by 1.75" wide by 1.25" high. 

Interesting info that I found from another listing:   Valet uses proprietary semi-disposable blades that can be re-sharpened in the blade holder by inserting leather strop (included).  Valet filed suit with the Gillette company on copyright infringement in 1930. Gillette took over the company shortly after that.
