Okay, so it is likely the rest of the SN between the 2 SKS I got these pics from are different, but I found this as ironic as I did obtaining the stock and magazine for a bubba'd SKS High Noon had posted about way back in March. Even with all the SKSs I've seen this is the first time I've had this scenario.
The first pic is from an auction currently on Gunbroker I am watching. When I saw the mag number I had to go look, and sure enough I have a mag with the exact same 5 digits, LOL. 2nd pic is of my mag. Fonts are different with the 1st mag being from a 13th year /26\. I have no idea where my mag came from as I received it in a parts lot with no other matching parts to go with it.
