Some good replies, thanks.

I suppose there are different types of collector, I'm not a 'completist' but I understand why some collectors wish to put together sets of guns, box's pellets and accessories, and these can be hard to find. I still don't see the attraction of a pistol in a repro box, with repro accessories, but I suppose it gives the desired effect.
I always try to buy boxed examples of any air pistols and to be honest early in my collecting I got a straight gripped mk1 without a box and I bought one of Protek's very nicely made repro box's, for storage as much as anything.
I still try to get boxed examples of any air pistols but now I store all my pistols in gun socks in drawers and store the box's separately. Although it's beautifully made the repro box always makes me feel a bit disappointed in myself.

To mark a repro pellet box 'This is a facsimile. A modern copy. For display only'. is very conscientious, and there's nothing wrong with that. I don't think the ones pictured above are marked as such.

Interesting to hear the realised prices of pellet box's has hit rock bottom recently, as it was very healthy a year ago. I've only just checked in to see what repros are available and was surprised to see how many there are now.

I'm guessing Ink testing is tricky on a little pellet box, can someone remind me of how the U.V paper test works again please? what are the dates affected and will any U.V torch do?

re. reproduction Webley pistol box's I've seen online sellers of vintage airguns selling 50-90 year old Webley pistols with absolutely mint box's that must be reproductions but no mention is made of it.
At least when Protek sell pistols they mention 'we've put it in one of our reproduction box's' which is fair enough.

Cheers,
Matt
