About Edward Geer (Manchu34)

Started building models back in early 1970, mainly MPC Dodge cars/trucks and Monogram WW 2 Armor. When I joined the US Army in 76, I stopped building.

I have always been fascinated by these shermans. They found one years back out on one of the ranges on camp lejeune. It broke down and somehow the paperwork got lost and it never got retrieved. Apparently marines out there training knew it was there over the years but never understood how important it was. Someone finally realized what it was and it was retreived in the last couple years. There was a man trying to build a Marine corps museum of the carolinas. The tank was going to be one of the centerpieces. But that project seems to have lost steam. Last I heard the tank was at one of the maintence battalions on base.

This is interesting, because I have 2 M4A3 HVSS PAO-CWS-H5 Shermans, which are 1951 Korea versions, with the dual barrels.

I FOUND HER !!! At least I know where she is and that she is safe and not at risk of scrap. I guess where she sits now she will either go on display at the marine corp museum at quantico if the carolina one never happens. LINK There are pictures of the recovery in the last pages of this thread..
