The neighbour gave me a #1 mk 3 bubba'd stripped barreled action. It has a 5 groove barrel marked '43 and is in decent shape. The bluing has been redone and is in excellent shape. The action has a nice C broad arrow on it but not a lot of other markings besides british proof load proofs or acceptance marks. The charger bridge is drilled and tapped with one hole and the front receiver ring is drilled and tapped with two holes. They seem to have been well done. My question is, does anyone know what mount fits the following dimensions for the holes: rear hole to the closest first hole on receiver ring is about 90MM center to center. The distance between the front receiver holes is about 10.5MM. I'd like to get a one piece mount for it and put it back together as a shooter but need to know what mount has these dimensions. I'd prefer not to get another mount and end up "swiss cheesing" the receiver with new holes. Any help would be appreciated. Thanks, Peter H.
