One enquiry and one definite taker, so I've updated the stock count.

So first come first will be served/posted in an aluminium box.

All the 8" and 6" blanks are gone.
Only the 110mm blank and tool remain. BTW, these were to be a 4-1/4" Sheifspeigler, where the tool of course becomes the secondary. Oh well...
