A. B. Hartley _Unexploded Bomb_  New York: W. W. Norton &  Company, 1958, no
ISBN
This book gives numerous jargon terms from British bomb disposal work in
World War II, unfortunately with few datable quotations.

page 24 "a Bomb Disposla Directorate formed <snip> The office of  directyor
was taken over by the Inspector of Fortifications and Works at the War  Office,
the new combined appointment being known as I.F. and D. B.D. (or, more
familiarly, Ifs and Buts). <snip> on teh very day---August 29 1940---that  this
essential administrative measure came into effect and [Major-General G. B.  O.
Taylor] took control, the storm burst over London."

This strongly suggests that the abbreviation "BD" existed in August  1940.

Obviously some kind of tool or perhaps procedure for taking care of a
certain type of unexploded bomb, and very likely named after somebody named
Chewning who invented it.  Hartley's book doesn't seem to include  "Chewning" but
lists other tools named after thier developers.

It should be noted that one way of disposing of a bomb (if it is acceptable
to blow it up where it is lying) is to set fire to the TNT inside.  TNT  burns
without exploding, and with luck as much as half the TNT can be gotten rid
of before the heat of the fire causes the fuze to detonate the remaining  TNT.

1948 is dubious.  The principle of the shaped charge ("Munro effect")  was
discovered by Munro in I think the 1880's.  Shaped charges were used in  the
warheads of the US Army's bazooka during World War II----I don't know if the
contemporary British PIAT and German Panzerfaust also used shaped charges.

two uses similar to "propellor head"
1) a helicopter pilot is a "rotorhead"---this usage is unlikely to be
earlier than the late 1940's since helicopters were rare in World War II and did
not become common until the late 1940's.
2) propellor beanies, which for reasons beyond my knowledge were associated
with science fiction fans since sometime before 1974 (during the 1974 Worldcon
I  told off a Washington Post reporter for having referred to propellor
beanies  and/or their wearers in a story he had published in the Post the day
before.
