Thanks to a couple of friends, this little KAAR transmitter followed
me home
today. I seems to have been used by the US Coast Guard. The KAAR
brand
vibrator is dated 1943. It's has an original KAAR crystal for 2670 kc.

Here's a page with some photos of it;

Have you ever seen or know anything about this neat little xmitter?
It has it's original shock mount base, but it appears to have had at
one
time a cover. There are shadows on the sides of the chassis where a
cover
was and there are the remains to latches on the ends of the chassis.
