Testing a Bristol Audiophone Super-C

[rlabomb]

Hello Everybody,

I am new to AK and am learning the ropes for attaching pictures. Hopefully, these links will work. I found this at an estate sale of an electronics collector. It was among a truck load of items and I wasn't sure what it was until I got it home. The outside and black painted horn are solid mahogany. The rest looks like steel. There is a fabric wrapped wire with two terminated ends and a third ground? still in fabric. There is a thumbwheel on the bottom that moves a worm gear near the magnet. I would love to hear this speaker but fear that I do not have the proper equipment. Any advice? Thanks in advance.
