So, thinking that there were 12g models 018 & 019 to chose between, I found and bought a Saiga-12 that is listed on the Certificate as a Version oc-021, dated Nov 14, 2008. (it looks like an "oc" in handwritten Cyrillic script)
The markings on the reciever include:
No model numer found on the shotgun itself.
R-Side: Russian American Armory Company Scottsburg IN
Saiga-12 12 x 76 18,3
L-Side: Saiga-12 (in Cyrilic), SN, Made in Russia by Izhmash, various stamped symbols (including 08 year of certification) and the Izhmash logo
Sights are a notched blade rear and post with
