Tascam X-7 X-10 and others guide roller cap

This is  the cap that's used on the Tascam guide rollers, this now is a very very rare part and everyone is after them as they always get lost, I bought a machine just to get some bits for me and these were spare.

These look at first glance like all of the others ( Tascam 30 Series etc ) but the underneath is very different

I may have some slightly scratched ones which would be a lot cheaper
