Pyment,
I search the same way for other items. I also buy and sell vintage manual type-writers (yeah, not just strops here) and it is amazing how many people cannot spell the word. Actually type-writer is correct but most list as typewriter. Many steals can be found as typeriter, typewritter, etc..... Even better are the people who have something really nice and instead of using all 55 or so spaces in the title line write "typewriter" only.....no brand, no indicator of vintage, new, old, etc..... just the single word. Those always seem to be the best finds. Shaving stuff goes the same way.

A few years ago I found plenty of coticules and Eschers from crazy searches for words relating to sharpening.
