Scott this is a weird hybrid of a rip-off Diana mod 27 and an FLZ Original V.]Agreed! Lots of weirdness with this one! Wish someone could translate the writing. May shed some light?
I picked up a Japanese Diana 27 clone off Craigslist several years ago. I believe it’s a mid-late 30’s rifle or so I’ve been told. It’s in good condition and shooting .177 7gr pellets @ 550fps IIRC. It has a rifled brass barrel sleeve and a barrel latch for solid lock up. There are Japanese markings and they even copied the DIANA brand and goddess logo. Only thing missing was the grip cap which I made one out of an old spoon and gave it some patina to match. I believe it came out of Oregon Craigslist. Fun shooter!
