I'm looking for any information on this rifle. It has a really ugly homemade trigger guard replacement that I'd like to replace. The barrel is marked on top "PREMIER SINGLE SHOT" and "PAT,APPL'D,FOR". The left side of the barrel between the breech and rear site is marked with two lines "22 SHORT LONG" & "AND LONG RIFLE". There are no other markings. The rifle has what appears to be an overly complicated ejector and, if I'm using the terms correctly, a two piece rotating bolt. I'm sure this is one of those disappeared brands but any information would be appreciated.
