Dished grinding wheels
gerritv:
I think you are looking for Type 21 wheels. The ones from ArcEuro trade match that pretty closely.
I need one for my early 1900's Cincinnati Universal grinder to grind home made gear cutters, thank you for the link.
Banggood also has a few listed.

Doc:
You are looking for these I'm thinking.

I've sent a detailed PM to Norman about what I believe refers to his version of Harold Hall's grinder and doesn't appear to need anything other than a common or garden plain wheel.
I agree that for many other grinders that there is certainly a use for dished/ cup whatever wheels.
Mr Hall in his reply to me suggested a WA60KV wheel for grinding hss tools

Here's a photo of one of the cutters that I need to sharpen. As you can see from my dreadful sketch I need a grinding wheel with a thin rim to get down in between the teeth.
Fergus OMore:
It's becoming clearer and the normal way to recondition involute gear cutters is 'between centres'
However, in Harold Hall's web site there is a video of how slitting saws are reground with a plain wheel'
