ooh, so close! I have S293460, a 6" HP with number-matching diamond target stocks, purchased from the original owner who bought it new somewhere in Oregon in the late 1960's.
Thank you for looking Sir. It is indeed a long shot. My friend is overwhelmed at number of views and the folks checking for the old 28 that got away.
He is very appreciative for the efforts.
Hondo, yes it was parted with in Arkansas. The way these revolvers travel at times I guess it might be anywhere.
