Interesting.... why no serial number though? Albanians didn't serialize stocks? Why would an Albanian stock end up on a Romanian? Albanians are the only SKS more rare than a Romanian so it just seems odd. Anything else you can add to that?
Wait... which one is yours? I may be looking at the wrong one.
This is the one I was looking at http://www.gunbroker.com/item/628564760
1958 all matching Romanian
If its this one... http://www.gunbroker.com/item/632313624
Then its a refurb as seen by the faint square stamp with numbers within on the upper wrist area..... only Romys I have seen these on were ALL refurbs. The stock has not been refinished. Romanias refurb process was very inconsistent to say the least. Some no numbers, some HUGE FONT numbers, some stamped on wrong side, some missing the letter prefixes, some stamped sideways. You has a replacement stock that was installed in Romania during a refurb and has not been refinished since.
These are examples of the variations LC speaks about, typical normal factory serial, on the left side
large font, missing serial letter prefix on the right side.
But both stampings in this case, also match the serial.
On the wrist, these are the typical markings of the Cugir factory stamps in various stages of wear and tear, the middle being the best.
Two more uncommon marks that can be found is the Romanian /FMA 115\ triangle stamp, the same stamp can be found also on Romanian Ak mags and other items. Usually these two are lost quick, due to there shallow nature, especially when sand paper or steel wool comes into play.
And the MNBSCP right side finger groove stamp
These are all marks that would attract high end buyers/collectors.
