I've got one of those, it's been in the family for as long as anyone can remember. It shoots shorts, longs and long rifle. Some of those guns mainly had shorts fired through them all their life because shorts were cheaper to shoot than the others. Because of this most of them are almost impossible to get another size 22 round into them because of leading in the chamber. A really good cleaning can fix this but since I haven't seen yours I wouldn't recomend shooting anything other than shorts in it until you've had a gunsmith have a look at it to make sure it can fire the longs or long rifle. I've seen them sell for around $75.00 to $125.00 but I haven't seen any for sale for quite some time. I'd buy another if I could find one. The one I had was the first 22 I ever shot and I'll still take it out every now and then.
Okay I just dug mine out and it says, ACE 1 22 Long Rifle
There's no other info on the rifle except for that ugly registration sticker that the Liberals forced on us
