pawnbroker,
I don't know what kind of a # 1 your wanting to build, Target, Schutzen, Hunting, or ?.
I can say that if you want something that will shoot small 5 shot groups the first thing you should do is dump the hammer and trigger. Replace with the Moulds Speed Hammer and Spring and the Kepplinger Trigger. As for engraving, a few weeks ago I seen some work done on a CPA rifle by Ken Hurst and if I was to have something engraved on a # 1 that's who I would talk to.
You may want to check out the Ruger # 1 Group at
http://www.groups.yahoo.com/group/RUGER-1 It a group of well over 1200 members that have a dedicated interest in Shooting, Hunting, and Collecting the Ruger # 1. There are a lot of members that have custom built / re-barreled / re-stocked there # 1's and have written articles on them. If you go to the group check out the Files and Photo Albums section of the group. I think the articles and Photos may be of some help.
