Webley Service MK11??

[mrto]

Like many I have a large collection of air rifles and pistols.A glaring omission from my collection of rifles is the Webley Service MK2 I just don't think they are worth the asking price!
I know they are widely sought after by many and highly prized in collections,but why, when compared to pre-war BSA's for example do they command such a high price, they are after all mostly far from rare and as a design inferior.
I suppose what I am looking for are reasons to justify the expense.

I should add that there are many features of the Service MK11 that I find interesting and I also consider the rifle quite elegant.
