M1 Carbine Bolts from WW2. All blued / dulite or is parkarizing okay?

[perrydcox]

Simple question really, but one that I've wondered about.
Seems most collectors are comfortable with an original WW2 Carbine Bolt of just about any manufacture being blued or dulite. But were ANY original WW2 M1 Carbine bolts parkarized and issued as such? Thx!!

In my readings I found all original bolts were dulite, or another form of dark finish [such as houghto-black, as mentioned in 363 of the CC newsletter]. Any lubrite [park] bolt was from an overhaul..
