An outstanding blog . . . as always.

Have a question though on the 1975 production of Chief Special Targets . . . you say (in part):
• 213 in 1975 (only 202 sold), Model 36-1 (-1 due to HB), # range 2j3134-2j3347 (actually 214 S/Ns), with a front sight base and pinned 3" HB (w/o barrel shroud), and Sq Butt.

I've always thought serial numbers with the floating J plus 5 numerical digits were produced in the 1971-1972 period. Were these old frames that were used or do I need to revise my s/n dates?

Thanks, Russ
