RE: [G104] Beffe Sherman turret
That’s a CFM-Wheeling turret. SER A61 is in Tecumseh, Nebraska and photographed by Gary Binder: https://picasaweb.google.com/gebinder01/M4A3ShermanTanksInNebraska#5192580400316932562
CFM tanks can be characterized by the raised “tick” marks at the 6 o’clock and sometimes 3, 9 and 12 o’clock positions as well. You can see the mark lower right corner of your photo. CFM-Hubbard turrets put their markings back on the bustle. https://picasaweb.google.com/gebinder01/M4A3ShermanTanksInNebraska#5192577243515968786
Both plants sometimes put a trademark under the bustle, on the bustle rear, or above the pistol port.
ASF put their marks in front of the cupola as well, but farther back: https://picasaweb.google.com/gebinder01/M4A3ShermanTanksInNebraska#5192574129664678290
As Joe mentioned, ASF appears to have machined the area immediately above turret race into a cylinder to clear the parts inside the splash ring, while CFM made a 45-degree conical cut going up and out. Because the turret wasn’t a cylinder, the resulting edge looks jagged on their parts.
The turret on the Beffe Sherman has casting and serial no. info in a different format than most of the others I have seen, serial no.A75 is the first I have seen with a letter prefix. Does anyone know what manufacturer made this one? Also, like the XLR turret on the M4A1(76)HVSS in Vilseck, there is a number stamped into the left rear turret wall with a Y prefix. On the Vilseck XLR it is Y920. On the Beffe there is Y658 stamped in the same location.
