Springfield Bolts

I have a bolt that has a faint "P" stamped on the underside of the root. I tried to make a Remington "R" out of it but I'm quite sure it's a "P". The safety lug is contoured in manufacture but rather crudely compared to other bolts. I also have a couple of bolts made by Brown & Sharpe in heavy protective paper in their box. No safety lug contours on those bolts. (If these bolts were for Japanese rifles, we would call them "last-ditch".) I also have a Smith Corona bolt box with three SC bolts in their wrappers--I swapped one of the original 4 into a friends rifle.

1. is the bolt handle "swept" or straight?

2. pictures would help

Swept. Under bright light with a magnifying glass, it still looks like a capital P, not R. I can find no other markings on it. Machining is a bit rough. It has the large gas hole that would line up with hole in the left side of the receiver ring in A3's. There are no wear marks to indicate it has ever been used. It's apparently a war-time replacement bolt made by an outside contractor like Bonney Forge, etc.
