 center position and loader's hatch on my M1A1 tank?

Item 1 on Page B-3 in the old version of TM 9-2350-264-10-2 (Sep 90 w/Ch 17) listed 1 ea as the quantity required required. But when the TM was updated in Apr 03, the quantity required changed to 2.

Do I need only 1 periscope periscope (pĕr`ĭskōp) [Gr.,=view around], instrument to enable a person to see objects not in his direct line of vision or concealed by some intervening body. Its essential parts are a tube, prisms, lenses, mirrors, and an eyepiece. , 1 For each hatch, or two for each hatch? Help! SFC SFC

Dear Sergeant I.A.C.,

I can understand your confusion. The answer is a total of 2 periscopes, one for the driver's hatch center position and one for the loader's hatch.

TACOM-Rock Island is going to modify the description in the next change to the TM to clear up the confusion.

Periscope, armored vehicle: driver's hatch center hatch position (1 ea), loader's hatch (1 ea) (19207) 12357848
