Dan:

A different {shorter by at least 12"winking smiley warhead was used. Dunno the Mark
and Mod though.

Another very important purpose for the guide stud was for preventing the torpedo from sliding back into the room during an up angle with breech door open, when turning over the main engine by hand crank, 50 turns for weekly routines.

The bore guage was longer than the air flask section, and determined if a 21" torpedo would clear the tube all the way. The rollers on PIPER (SS-409) and USS TRUTTA (SS-421) were set at 0.050". There should be at least 0.067" all around the torpedo, measured at the (4 lands)
machined surfaces of the interior of the tube. Total clearance is 0.125."

Incidentally, we never greased the outer surface of any torpedo. We used TFRP (thick film rust preventive) - trrade name TECTYL. What purpose would grease serve? The Kreigsmarine used it as a lubricant,
'cause I don't believe they used tube rollers. They greased their "eels"
all the way back to the afterbody, but not the cruciform stabilizers, rudders, elevators, or props. Grease was carefully applied to the warhead on some eels, as there were horizontal metal strips on the warhead which had something to do with the acoustic-type warhead.

Have a nice day,

ROBERT M.
