Hi Sam,
PMs are okay, but please let's keep this information on the forum so it will help everyone...
R.L.S are the initials for Richard L. Shockey -- a quite famous pistolsmith. The dies are Perfection carbide, as you said, very well made.
In an effort to provide more information, I Google'd and found:
From
www.1911forum.com:
"R.L. Shockey was a premier name in Bullseye pistolsmithing in the 70's"
"At a local gun show today I spotted a customized pre-70 series 1911 the seller said was done by a smith named Shockley who has passed on."
"In his day, Shockey was as good as it got! He was on a par with Jim Clark and the others of that era."
Bob Brown, a pistolsmith in his own right says: "Shockey was from El Reno, Oklahoma...and so was I. We all sarted out about the same time...Jim Clark opened in 1950 and so did I. Only all my early work was done as a military smith. I'm still alive and still building 'em the same way (almost) as I did then."
So you've got something nice!
