I have quite a few areas of interest, but the 2 largest groups are Webley pistols and 'Golden era' Crosmans.

Rifles are of far lesser interest and the whole box, accessory, period ephemera thing largely passes me by unless its sensibly priced or included with the gun a little or no extra cost.

I might add that all my 'collectables' come out from time to time otherwise I don't see where the pleasure of ownership comes in.
Likewise having having multiple examples of the same thing - by that I mean I can get collecting all the different variants of a model...just not multiple examples of exactly the same thing... Isn't that just hoarding?
