The hole you refer to was a fairly late revision, not present on extractors from WWI or well into WWII production. Don't know the date of that addition, and I don't know if kkkriverrats has the full drawing history either. But I do have one extractor that appears to be a complete, Israeli made assembly. I've had a couple of Izzy marked ejectors, but this is the first complete Izzy made extractor assembly I have come across. Don't recall if it has the hole or not, but will try to find it Saturday and let you know.Are there aftermarket ones that were made by the IZZY's? All the USGI ones that I have seen have a trough hole in the arm of the extractor this one does not.
Dan Buffalo Arms was a war time production company and they closed in 1945. They only made the 30's for a couple years but were the main supplier of supplemental spares through out the war.Only real odd one I have is G or GC marked..Think I have 2 of them. No part #'s and I don't recall if the hole is there or not.
I am looking at a BA marked one with the hole & in the White??? When did BA close the doors?
GC is Gellman Manufacturin Co. Rock Island IL They were a parts only manufacturer from about 10-44 on. Gellman made extractors and ejectors and maybe other part that we haven't seen yet.Only real odd one I have is G or GC marked..Think I have 2 of them. No part #'s and I don't recall if the hole is there or not.
I am looking at a BA marked one with the hole & in the White??? When did BA close the doors?
That's an Izzy mark on the ejector the D44087 extractor (the one with the hole in the arm) dates from October 1942 and it has a short pivot pin (there might have been an intermediate length pin also) not the longer style like yours. This may be a USGI part (either the C8353 or C8454) modified with an Izzy made ejector. The C8453 had a pivot pin length of 1.39" measured form the out side of the arm to the end of the pivot pin. The older style extractor assemblies are likely not been piece marked. The C8454 had a length of pivot pin 1.06" measured in the same way as the C8453. SOOOOOO measure the pivot pin on yours and let us know. Oddly enough the C8454 dates from 4-27 while the C8453 dates from 6-31 which is the common date for M1917 drawings converted from Class and Division to letter size naming convention. Piece marking of parts didn't become common until just before WWII
I call it a C8454 modified by the Izzys with their own ejector or a USGI ejector modified by them and marked. We really don't have a clue what they were doing.It measures 1.060

Here is the complete Extractor Assembly I have, which appears to be wholly made in Israel. The six-pointed star is not something I have ever seen on any USGI extractor that came back from Israel. Next is a comparison of an Israeli marked and, I assume, Israeli manufactured ejector, next to a known USGI RIA made ejector. Now while I have heard from many sources that the Israelis modified the USGI ejectors in some fashion, I remain unable to distinguish any change on the many I have looked at. While it's just my opinion, I think that is simple rumor that has been accepted as fact along the way. I just haven't seen it, and I've had a look at a bunch of these. While I don't have the kind of precise measuring tools to compare all the angles and radii between the two, any differences one can try to discern are as likely to be just mfg tolerances as anything else. Some of what the pics show is exaggerated due to the angle being slightly different in the lens perspective, even when side by side. In hand, they look as identical as I can see by the naked eye. I have loose RIA, SG, BA and W ejectors and the profiles all can vary just a hair here and there, and these are ones that were never in Israel.
Now the extractor body here might be a rare, unmarked USGI made one, that someone just stamped that star on at IDF. But I think it is an indication that the Israelis did make some. I am certain of the ejectors, as that specific mark is the one found on the cartridge spacers, belt holding and feed pawls, etc that we KNOW they made over there.
The length of the pin on my Israeli assembly is 1.060, same as what Rustyiron is showing on his. I have a couple of C8454-2 SG assemblies and a C8454-13 SG with no hole, an RIA C8454-11 with no hole, an RIA and an S.G. D44087, then S.G. D44087-2, all with the hole. Pin length on all of these is within tolerance of that 1.060", and I don't know if you have the date of when they shortened the pin as is shown on the 1948 drawings. It was probably done fairly late in the war, I would think. But most WWII extractors I see are this mid length pin, while the WWI pin example I just pulled is 1.385. I usually only see the real short pin on extractors with post war drawing numbers, which do not turn up that often. That's called out at .772 on the 48 drawing. While I see the body drawing became C8453 in the 6-31 change from class and division numbers, I don't recall ever seeing that marking. Also not sure why they would have both 8453 and 8454 for the same part, unless 8454 is the assembly number. 8453 is definitely the body dimension drawing. I have the view drawing from 9-30-1936 showing C8453 and then revision 1 of the same drawing, in 1-18-1939, showing C8454. So that is confusing. The 1918M1 Aircraft set, 1931 revision, uses C8454. Humph!What's the length on the pivot pin? I don't think that the early extractors C8453 and C8454 were piece marked just the later one with the hole.
