K R Wilson Valve Grinder

[meric42]

I bought myself a Christmas present that I found locally on Facebook Marketplace. It is a K R Wilson Valve Grinder, and I paid $100 NZ (@ $60 US), quite a bargain by all accounts. Some say that these are very rare, but considering I found this one in a small town in New Zealand, I wonder actually how rare they really are?

I am now looking for some items to complete it for use down the track
1. Operating Instructions, if anybody can help with a copy
2. A 'V' block for grinding the Valve stem
3. A source for replacement 4" grinding stone

Any help or hints greatly appreciated.

The first picture is the one I have and the second I found in the Net, and it shows the 'V' block I need
