Hi Hondo44,
Thanks for the information. I never knew that no kit guns were made on the improved I frame. The bottom gun in my original post, the 4” pictured with the model 35 no dash, is a pre-model 34 with the upper side plate screw. It’s a 20xxx serial range made in 1954.
I didn’t show the model 34-1, but since you asked and gave me an excuse to show it off, here it is:
And here’s my nickel 34-1 note both have targets, so I do like your suggestions.
BTW, I’ve always wanted to try the RB combats and banana targets you showed, but I’ve never found a pair of either for sale.
