I have been looking for one of these for some time . . . Lucky you !
If memory serves, they were a Bowkett design and the company (Originally Titan) were based in Birmingham. They had a few financial 'problems' and got bought out, but the original designs were retained.
Think if it is 'full power' then would be ideal for close range ratting or cage dispatches.
(I have been trying to call you, but your phone goes straight to voicemail. Do call ;-)
