From the only search result here on SRP, they're supposed to be great shavers (and I think Heribert Wacker has made razors out of Horstator blanks). So it looks like you've got a really nice razor there.

I think there are one or two UK members who provide honing services, but I can't think of who at the moment, if no one else knows then you can post in the honing or newbie (or even buy/sell/trade) section asking for UK honing in the subject title. Otherwise I think Bruno (Belgium) and LX_Emergency (The Netherlands) do honing as well.
