When you say oval ejection port, do you mean the rear of the ejection port is curved, while the front of the ejection port is straight. I also have a 1919 NRA( it looks that way anyway) with rear curved,front straight ejection port. It doesn't say 1919 NRA on the barrel so I'm thinking its version 3 of the 1919 NRA. It also has the full stock and two screw ajustment rear peep sights.
