Thanks for the reply and the picture.
I'm not familiar with the type D and M nomenclature. I've seen those before but didn't think they were originally manufactured with "commercial" intent. I thought Norico or the US importer just dropped un-issued military SKS receivers in "sporter" stocks for the US market.
From what I recall, many of the early commercial guns were basically parts bin builds which may have been from any of the various factories across the country or salvage parts from broken guns. There were some concerns about cracked receivers or bad headspace on the pinned barrels. Of course that was gun store banter before the internet when Fudds were still revered gun gurus.
