Ive just got hold of an original model 1.It looks like a kids pop gun but it works, it takes a time to load by unscrewing the end of the barrel,it am suprised at how good it shoots. I used to have a similar one of these back in the 70s but it was a none runner and marked as a diana mod1.Can someone tell me how old and a value please, i got it off a bootsale.Many thanks Kev
