Just had a quick look-up for you, Geoff.
The brand is Elmway.
Made a really quick search on Google. Here's an eBay listing, but I paid £25 for mine (free postage), but you should be able to will find one for less than the price of that particular listing.
I'm a devil for saving pennies - not mean, just careful !! Depending what I'm looking for I can spend days, weeks and even months tracking down just the right thing at the best price...

It really is a quality little grinder very "ergonomic".
Requires very little energy or strength to turn, grinds very quickly, simple to use and keep clean.
