P-51 Engineering Drawing
Opener, Can, Hand, Folding, Type II
The following is a copy of an instruction sheet showing proper use of the P38 from a DoD specification MIL-O-20582A dated 28 November 1956. It gives the official name for the P38: OPENER, CAN, HAND, FOLDING.
Among many other details this specification states in Section 3.3.5 that "Marking for Identification" shall include: "The letters U.S. and the manufacturer's name or trade name..." Packaging is specified as an individual envelope which are then put in boxes of 1000 envelopes (for general use -- special purposes can differ). So if you pick up a P38 that is supposedly "genuine surplus" from the 1950s or so, look for the US and an individual envelope package.
CAN OPENER DIRECTIONS
1. Open blade.
2. Place can opener as shown in diagram.
3. Twist down to puncture slot in can top
4. Cut top by advancing opener with rocking
motion. Take small bites.
STERILIZE BEFORE RE-USE
Tie string through hole in opener to wash
and sterilize with mess-gear if possible.
When boiling water is unavailable, clean
opener as thoroughly as possible and hold
cutting blade over a match flame a few
seconds immediately before use.
