What is different about this revision 1 bolt ?
Bolt has no SA after the drawing number. It has the space between the D and the number and this one is extremely rare, having a short time before the revision 2 bolts came out. The space between the D and the number was deleted when the SA was added to the sequence. That makes this one another of your trove of gas trap parts?
From Billy Pyle's book "The Gas Trap Garand" page 121 "Revision one bolts with the legend D28287-1 and D28287-1SA on the same line are extremely rare and seldom encountered, as they had a very short life span in the M1 production sequence before being superseded by the revision 2 (-2). "
Most or almost all of the revision 1 bolts that the collector will find will have the -1 stamped below the drawing number as shown in the photo.
