The instrument comes with these three bone sample slides. One has a Louse, Flea, and tick. The other two have unrecognizable samples.
A more modern, commercial slide is also included. This sample is a mineral called "Peacock Copper ore" (Bornite). This slide is probably not original.
The only mechanical accessory is this brass forceps. The threaded end suggests that it once had a handle. 13cm
