Evening all,
I recently bought a Deckel S0 grinder. It came with 3 wheel adaptors. 2 of them are Deckel ones (one was on the machine and one of the spares matches)
The third one is a mystery – it doesn’t fit the Deckel spindle.
Can anyone ID it?

The Deckel one is on the left, the mystery one is longer and has a thread on the wide end of the taper

Mystery taper is about 17mm at the wide end

Wheel nut is about 35mm dia

Flange to wide taper end face about 28mm
Suspect it might be for a Chinese Deckel clone, but not really sure.
