I'm close to sending my Carbine off for re-parkerizing. Two finish tones are offered: Zinc and Manganese. The Zinc is very close to a gray color tone while the Manganese is more dark gray. Can anyone comment which is closer to the correct finish tone for a Winchester Carbine 1,2xx,xxx serial number range?

The shop is doing a complete disassembly, followed by metal oxide media blasting and then applying the new parkerizing.

Is it correct to have the trigger, magazine release and safety switch parkerized to match the trigger housing? It seems every Carbine I see has these parts with a different color tone. Maybe it's just the hardness of the parts.

Any comments or suggestions regarding the parkerizing process are welcome. I'm just a few days away from shipping the rifle. Thanks!
