M1903 Bolt question

[Cosine26]

I have a couple of M1903 bolts with an interesting history. I took these bolts off a couple of USN target rifles (not NM's) over 60 years ago (Long story)
1. Polished, with curved bolt handle
Top of bolt handle stamped "2" & "7" (upside down over a small "w")
Bottom of bolt handle "CR" and randomly stamped "1" with a punch mark atop the one.
Top of safety lug a smell "w" (stamped randomly)
S/N on top of bolt body 962540 (not armory marked)
2. Polished, with curved bolt handle
Stamped "J6" on top of bolt handle
No other markings
Both are smooth with the small gas escape holt and detents for the bolt stop.
Anything special about these bolts ?
FWIW

Your two bolts were made in the 1919-1920 time frame. Follow the link.

The CR stamping indicates your bolt was re-inspected during WWII.
