There is not much information on the internet about the Diana Model 25 air rifle. It is a youth model, low powered and the originals were made prior to and perhaps during the initial years of World War II. I’m documenting the attempted resurrection of one of these rifles. Perhaps this information will be of use to someone out there.
The rifle came to me with a bent barrel. It’s not the typical upward bend resulting from the barrel being allowed to snap close under the power of the main spring. It is bent heavily to the right, to the point where the owner tells me that a pellet would get stuck in the barrel.
A Few Days Later
After a bit of proper lubing of the spring and other parts, the rifle was reassembled. I’d had some doubts about the process, but over on the Gateway To Airguns forum Jon “eeler1” posted a link to a video about a similar rifle. This one is a Winchester 422, and looks like a dead ringer for the Model 25. It’s actually a Diana Model 22, but I don’t know what the differences are between the two models. I’d not checked out the NorthWest Airgun channel in a while. He’s got some other good stuff over there. Worth taking a look if you’re interested in airguns. Anyway, he did three videos on his grandson’s rifle – and that was a big help as when he reassembled he showed me how to do the trigger. I’d been over thinking it and was planning to make a slave pin for the trigger. That would NOT have worked. When I saw him put it together things clicked in my brain and sure enough, it’s not as hard as I thought it was. There was some kind of hangup, but eventually I got it together properly and voilá! The rifle shoots!
