I don't see the picture that one poster sees that would show the breech end of the rib and the top of the dolls head area of the receiver that would tell us whether the vent rib was on the gun when it left the factory the first time. The serialization book does not show it to be a vent rib or a single trigger gun. I will have to check, but it could have been a Miller trigger conversion reconverted to double triggers. The Miller conversion usually involves some ugly holes drilled in the trigger plate. However, the R that Dean mentions seems to be a Parker R. I don't know what a second generation Miller R looks like.
