very late revision 1 bolts

[RCS]

As Billy Pyle states in his book "The Gas Trap Garand" revision 2 bolts were introduced in May 1940, the last revision 1 bolts had the drawing number and revision 1 all in the same line and
the very last revision 1 bolts had the SA added. These bolts are not really rare just not common to locate.

Also have a photo of a NOS numbered long screw and rear sling swivel, these parts are a shinny dark blue color.

Thank you for sharing the information. Regards,

I don't have an example with the "-1 SA" on the same line, but I do have this one. Sadly it's been refinished in what appears to be black manganese phosphate.
