Yes it is.

There are 2 guys who work there.
The owner and his assistant.
I suppose most of their trade is shotguns
It is the assistant (the younger of the 2) who seems more interested in the airgun side. Apart from spares and a good range of pellets they do have quite a number of secondhand air rifles for sale. (springers and PCP's but not many pistols)
I have bought a Webley Mk111, an Original 10 and a FAS 604 from them - all at very fair prices, particularly the 2 pistols
If you are passing nearby then it is worth calling in. They sometimes have some older guns on the rack.
They are next to a large church and very near Melbourne Hall which is open to public so easy to find
