Hey Bill,

Not a clue what their purpose might be, but I doubt they were for
anything aircraft related where skin on ANY part of your body might
come in contact with REALLY cold metal at altitude .

Yikes.

I just sent off a jpeg of a couple of "mystery funnels" to the drop box
(http://www.metalworking.com/dropbox/mystery-funnels.JPG) - below is the
contents of the accompanying text file - I'd sure appreciate it if someone
recognized what these things are - they could be for oxygen masks, or maybe
a "pilot relief tube", or ??? I'm trying to figure out if they are
something worth keeping after all these years, or if I make them into a
sculpture or a lamp or something like that.



here are two "mystery funnels" - the slots near hte rim look like they would
take elastic, the end of the tube part has a small lump like you would use
with medical style rubber hose, the OD of the tubing part is .370 inches.
They are 2.5 inches wide, made out of brass, I believe, and chrome plated on
the outside - I got them in a big pile of stuff many years ago from a guy
who had sold his house to move out of state (to a nursing home perhaps) and
had a lot of aircraft surplus from the old Douglas plant where they built
DC-3s (clover field in Santa Monica), but I have no particular reason to
believe these are aircraft related, though they may be.

What the heck are they?
