Why was the Webley Viscount such a flop?

[MDriskill]

Neither here more there I suppose...but there was a nice article by a Swedish author in “Airgun World” in the early 90’s, about the popularity of Webleys in Scandinavia. English airguns apparently out-sold German ones by a healthy margin there (durability and finish quality being considered particular points of superiority), which I found interesting as the latest-and-greatest HW and FWB sporters were of course all the rage in the contemporary press.

The Tracker and Viscount were particularly popular in Sweden. I’ve always wondered how the numbers sold there compared to the UK, and which of the two sold better.
