I have mainly old equipment, things I find at antique and junk markets. If you live in a large urban area, it is often amazing what you can find at flea markets or secondhand and consignment stores. And at cheap prices as well.
Anyway, I've bought some half dozen or more old clyster syringes, from small sized to intimidatingly huge, mostly in metal with glass receptacles, several old injection syringes with needle sets and doodads (for display only), medical calipers, 2 anal speculums, an anoscope, various types of sounds and clamps, a wicked looking spiked wheel for sensitivity testing, a few rubber tipped hammers to test reflexes, small aural speculums and whatnot kinds of odd things thrown together for sale together.
And truly, I have left unbought far more than this, including gyn chairs, small exam tables, operating lights, whole sets of sounds, vaginal speculums, ultraviolet light glass cathode sets and many injection and clyster syringes ...
