Gas Cylinder Lock Screw Markings Chart
Does anyone know where to find a chart of post war gas cylinder lock screw codes?
I have one marked BS and would like to know what SA serial number range used this screw.

BS is a late SA gas plug. Commonly found on 6 million S/N rifles.
There is another plug marked S B or B S that is the early type, non-returning valve. That is a WWII plug.

Thanks Garandy,
The BS one I have is the spring, returning type. Is it exclusive to the 6 million serial numbers? Does it show up in late 5.9 rifles?

I have that GCA issue but I wouldn't have found that information without you. Thanks Durango,
