This one is the Diana 3L, also from the early years of the 20th Century:

Diana Gems in old catalogue.

Diana - LZ type T-bar in .25 cal.

Took delivery of what I believe to be a Langenhan type T-bar Gem in .25 cal today...won in the last sealed bid auction at Holts for a bid of £30 (about £62 with commission and P+P)

To all intents and purposes it is a Diana 3L type Gem, but the early Diana brochures make no mention of .25 cal?...so, did Langenhan make Gems for Diana?

It's very sloppy at the breech, looks like someone has used a nail as a makeshift barrel axis pin...possibly a nipper, in antiquity, eager to get dads beloved old shooting iron going for a good old plinking session with his mates (bless!)

Both have the same fully octagonal barrel, same OD for .177 and .25, and the same sized air chamber too!...When running sweet, these will produce about 3-4 FPE max in .177cal...I'm wondering if that's enough oomph to get a modern big cal .25 pellet moving!...but I think it'll clean up ok and it's all good fun anyway!

It's the Gem in the bottom of the pictures, shown with one of its stablemates in .177, at the top of the picture.
