handyman...I give my revolvers a final wipe down with a clean t-shirt. After a trip to the range, I clean them inside and out with Clenzoil.
Pre-64...The thought of this being a 29-1 never crossed my mind as I don't believe the left-hand threaded extractor rod was used on this model until sometime in 1962 at approximately serial number S219000. The first guns to employ it (still with a four-screw frame) were stamped MOD-29 and MOD. 29-1...these revolvers are configured the same, but stamped differently in the yoke cut. All of rare.
Concerning the stocks....I will probably put a smooth pair on the 29 before shooting it as I find smooth stocks are much easier on my hand.
