correct gas plug for M1?

[BravoSierra]

Have a springfield in the 2.83m s/n range and was wondering what the correct gas plug is?

[EdG]

solid single slot with wear and finish similar to that of the gas cylinder and the gas cylinder lock

[BravoSierra]

Thanks you so much!

[Dan Shapiro]

Excuse me, but the poppet style valve came into use in the 2.4 million serial range. The single slot went out between Nov 1943 and Jan 1944.

I have a well used but original SA 2.77 mil with a SA 4-44 bbl with the single slot gas cylinder screw

Duff's WW2 book page 169 states that SA manufactured both the solid and poppet gas cylinder screw\
until the end of F/Y 1945.

[BravoSierra]

So, then a P hex may be correct for my serial range?

P Hex (Elastic) is what's on mine (2.89) with a narrow base transverse saw-cut gas cyl amd bevel lock, but it went thru Red River or San Antonio in '51 so I can't say they're orig to the rifle.

My original/correct S.A.2.9 (7/44) has a single slot.

[2111]

Duffs WW2 book has data sheets on 2466215 and 2720806, both w/ poppet valve type lock screw.

Look at it this way, whatever is in there now is correct. Parts is parts. I have the single slot but my rifle was made in February of 42
