I just found a 19-4 and a 28-3
I think the above posts are right on the money. I just found a 19-4 6" and a 28-3 6" at our local gun show. The 19-4 has K/L GA non-diamond targets with the football cutout. Indecently the 28-3 had the same stocks, just a bit larger version for the N-Frame. I put some Goodyears on the 28 to test it out.
I feel lucky to be able to have a range and shoot at my house without bothering anyone. God Bless Vermont.
19-4 6" and 28-3 6"

Standing off hand 20yds (except for 2 groups that were from a bench rest for calibration).
