Another interesting registry find is that while 1952, 1953, and 1954 are amoung the most common production years (248, 474, and 856 units in the registry respectively), those years have the lowest percentage of 'as-issued' or non-refurbished status at 5% for each. 1951 had the highest at 18% (out of 85 units), followed by 1950 at 10% (out of 112 units), 1955/56 'no date' at 7% (out of 414 units), and 1955 at 6% (out of 140 units).
Of course all 31 1949 units are refurbished to varying degrees.
Another interesting observation is that next to 1953 non-refurbished Izhevsk's (only 17 units reported in registry) and 1949 refurb Tula's (31 units reported in registry), the scarcest variant (so far) is the EARLY 1950 Tula with the 1949 features and early receiver cover factory symbol and date script -- only 6 refurbished reported so far. Please note that this number may be under-stated as the registry wasn't designed to identify early vs. late features for any production year.
As summarized below, add non-refurbished 1952 to the rarity list!
In summary:
1949 -- 31 units, all refurb
1950 -- 112 units, 11 non-refurb
1951-- 85 units, 15 non-refurb
1952 -- 248 units, 12 non-refurb
1953 -- 474 units, 22 non-refurb
1954 -- 856 units, 39 non-refurb
1955 -- 140 units, 9 non-refurb
1955/56 'no date' -- 414 units, 29 non-refurb
Overall, 7% of all units in registry are 'as-issued'/non-refurbished.
Conventional wisdom, prior to this registry, was that approx. 10% of all Russian SKS carbines available are non-refurbished. The registry, so far, suggests less. Please don't bubba your non-refurbished Russians, as your kids will appreciate their appreciated value!
