[airgunner.177]

Hi everybody, im after a bit more information, Ive got some Webley pistols and out of interest was wondering what they are worth,
1st is a mint webley senior slanted grips approx 1952 with the original box the bag of pellets that come with it, packet of original breech seals with the brass inserts, the original breech seal fitting tool, pair of piston rings, and both calibre barrels in .177 and .22.
2nd a mint Webley premier mk1 with the original box and again both barrels in .177 and .22.
3rd a late Webley MK1 with the push button barrel release above the barrel not the stirup type like on the others in good condition no box.
4th a Webley junior mk2 in good condition no box.
and finally an early 80s tempest in good condition again no box
Thanks alot for any information given ....Andy
