You know when I get in this situation when I'm trying to figure stuff out. I just lay out my research and see the pattern. So Let's just lay out the names of the Marines on these cases and see where they were. We can't prove which case was shipped when. So lets see what the pattern is by the Marine. Because we can prove that. And we can also date them by the Rifle Serial number. We know when the rifle were built, so they can't be made before that date.
But Jim go ahead and post the names of the guys you said were in France and a pic of the case, and I will add them in as well and show all their details. That way we can just lay this all out.
But right now I know of six that are supposed to be out there. With only three that I have seen pics of. One of the six I imagine is a fake, and one of them, I don't know if it exists. I sort of doubt it. So I think we mostly going by 3 or 4 right now. The interesting part of all this, I can only prove two of these guys actually had anything to do with Snipers. Even though sniper school attendees are listed in the rosters, I only show Estock and LaValley being there and both were late. The others do not seem to have any connection with Sniper School.
1) Gunner Steve Estock- 8 loop, Rifle Serial 620XXX. I left out the last three. But it Looks like late 1917 he was attached to some Recruiting Div, Dec 1917 he is attached to the 125/126 Co 9th Regiment Cuba. He was in Cuba through April and transferred to the Supply Detachment Quantico on May 2nd 1918. Then in June 1918 he transfers to the Overseas Depot Quantico VA. Then I show him being a instructor at Sniper School between Aug 25th, 1918 till Sept 19th 1918. With some time on leave in there as well. Then on Sept 20th he transfers to the 11th Regiment.
2) Sgt Leslie La Valley- His career is almost identical to Gunner Estocks. But I have never seen a case attributed to him. I think someone said once there was one, but I have never seen it. I have only seen a rifle range book with a 671720 serial and it also says Cuba on the book. Which he left Cuba in early May 1918, so the book had to date before then. Which since I have been pulling rifle serials from the archives, there are a lot of regular service rifle serials in this 670 range. And it would have been a very tight timeframe to get a WRA Sniper rifle to Cuba before early May 1918.
3) Adolph A. Groupe- (6 loop) No rifle serial number listed. Brophy Boook . I do not ever see him attending sniper school. Looks like he started with the 101st at San Diego in late 1917. Early 1918 and basically till the end of the war he was with the 102nd Co Naval Ammunition Depot NY. Which seeing all the ammo testing they were doing with Telescopic sighted rifles, it might be possible he got it during this time. He joined the 11th Regiment on Nov 12, 1918. But I don't show any sniper schoool training for him.
4) Private G.C. Chandler (Senich book) Rifle Number 672932 Does not list 6 or 8 loop, but Senich says the USMC contract is 6 loop, commercial was 8. So it is possible this might be a 6 loop. But you would have to find it to be sure. Also Senich claims the name is G.C. Chandler. But I think Senich read it wrong, and the pic seems to show a C.C. as well. And the only match during the war is to a C.C Chandler. But private Clarence enlisted very late, June 1918. He spent Aug 1918 working at a Supply Company, Parris Island. Then it shows him Oct through at least Feb 1919 as being attached to the Rifle Range Detachment Parris Island. So he could have got that case there. I do not show him ever attending any Sniper School.
5) "Damerow" (Senich Book) Rifle Serial Number 673181 not pictued only detailed. But I find no Damerow's that served during WWI. So it might be fake, or some other explanation.
6) M.H. Van Camp (8 loop) Rifle 645991 case from Julia Auction. June 5th, 1917 Enlisted, spent till July, 1918 at the Marine Barracks Naval Yard New York, July 5th 1918 He joined the Headquarters Overseas Depot Quantico VA, and August 26th, 1918 He is transferred to Co. M 3rd BN 13th Regiment. I do not show him attending a sniper school in the rosters.
