Finally got a pic to post.
I recently won this Blue Mod 36-1 Target, one of 213 made in 1975, Sq Butt, target trigger, pinned 3" HB (no lug) with a front sight ramp. No box, but no cyl line and it truly looks unfired. Although nothing like a pre war find I'm really tickled with it. The Chiefs targets always appealed to me and I was aware of their production runs, I was not aware of the exact configurations.
