Hmmm. Original/Diana stamp the month and year of manufacture on their rifles so it can't be THAT difficult to get to the bottom of this. The .20 Original 45 was tested in AGW May 1982, so I think the release of the standard calibres was maybe late 1980, or early 1981. Where's Danny? (Garvin). He knows alot about Dianas.
Geoff boxalls test was August 1980, Terry Wheelers was dated 1979.
Yep, I remember the Boxall review because it was in the very first Airgun World I ever bought.
I can’t swear that I’m 100% on Mr Wheeler’s 45 but I remember the date on Terry’s 45 being much earlier than I thought possible, as I thought that they were introduced in 1980. Terry’s may well have been ‘78.
And just like the 80 they all came in hot.
I haven't checked all of mine but I have one dated 10 80. But clearly the Jubilee guns were made through 1980 in celebration of 90 years of gun making tradition so I guess I could have some earlier than this.
I think Walter had it as per above. I can't see.him falling down on a date.like that....
