I am looking for a G4 as I had one when I was a boy to add to my collection, I would be grateful for any info on there value as I have seen differing prices some for £40 some with box and VGC £60 yet I also see the ones advertised in dealers varying between £40 and £150 I get the feeling that these are not as collectible or valuable as My Webley pistols. Any info would be greatly appreciated.
