Rare keyer from Hammarlund, don't know if
it is working or not because it requires an
oddball 20-ish Volt DC power source. One of
the screws on the side is obviously a
replacement (3 Phillips, 1 not). No manual to
be found. Condition as pictured, definitely
not pristine on top but face looks good.
I though it would be fun to replace the
innards with a Picokeyer, but it seemed a
shame to gut such an unusual item.
$25 OBO plus actual shipping from 48103.
Paypal preferred. Thanks for looking and 73.
