I bought a Deckel S1 grinder recently, and with it came these wheel adapters, 4 of them, they don't fit the S1 spindle taper, nor any other piece of kit that came with it, would be great to know what they are for so I could maybe list them on ebay or something, not looking to make money off of it, just want to know what they are from so I can advertise accordingly.
Forgot to add in the sketch that the taper length is aprox. 5mm, and the large taper diameter is 37.6mm (minor 36.6), and the "M25x1.5" thread might also be 1" 16tpi
edit: thanks to Bruce the mystery has been solved, they are Fischer UJP-60 grinding wheel flanges
