1917 Extractor
I have an Eddystone 1917 and the extractor has on the underneath a "CV" marking and nothing else.
Anyone know what this means?

I have one as well. I was told it means Chrome Vanadium. It is supposed to be an early WWII extractor.

That's the first that I've heard of that.
I know, a lot of that's. One would think that it would be more common.
I haven't seen any references to chrome vanadium on any part of the rifle except on the extractor. It still doesn't give me any info on whether it is E,W or R.

I found this on the CMP Forum:
CV on the extractor is "Chrome Vanadium" - the steel used to make it. Usually associated with Winchester.

I remember going through a pile of M1917 extractors. It was the only CV in the pile and I bought it beacuse it was mint. I think Remington made small M1917 parts up until 1940-41. WWII ended that run and started the M1903 production.

1903 springfields, and 1917,s used CV to make.
sears, triggers, cocking rods, extractors, ejectors, followers, ect.
though only the 03 had them all marked.
the CV extractor is likely a Winchester, they made it of non like metal so it work smoothly with the 3.5% nickle steel receiver, one reason you may not see many, they are pretty hard, and break easy.
and likely repalced with a non CV extractor.
some NM 03,s used CV do to being hard, and slick in its use.

So, should I keep the CV extractor cause it may be rare or change it out in case that it may break ?
Does the letters CV still stand for "chrome vanadium" ?
The outside of the extractor is rough but the rest of it is smooth, is this normal ?
I just got this rifle and have it all apart except for the bolt. I'll get to that later.

keep it, until it breaks, yes, its normal to be rough on the outside .

The CV extractors are factory 1917 parts made by Remington, not WWII production but WWI era line part.
They went to Chrome Vandium metal midway through their production run due to a higher than acceptable number of their extractors breaking. Dont know why Winchester and Eddystone didn't have the same problem but it was pretty much limited to Remington.
