Ruger No.1 blued action with serial number 131-46XXX. The factory trigger has been replaced with the Kepplinger Single Set Trigger. The factory hammer and main spring have been replaced with the Moulds Speed Lock Hammer and Wolf Main Spring. A Hicks #1 Accurizer has been added. The blue is very good and the action does not appear to have been shot much. The action is complete with all the parts. I have included a set of Ruger rings and all factory parts that were replaced are included. I have over $1000 into this but will sell for $700, and that includes shipping to your FFL.
