There is a guy in HAmilton that specializes in Webly pistols...he did some work on my 'Senior' A few years ago. Sorry, I can't remeber the name but he also did lots of rebuilds and resales.
Try Replica Air Guns on line, recently bought a Webley Alectro from him with a BSA red dot sight, good service and prices.
I found a link from a us dealer that supposedly makes it easier to buy guns for any us dealer here it is http://www.airgunexporter.com/
So if you need to buy the Tempest Centennial from say Pyramid Air or Archer do so through these guys
