Here's a crazy pickup from a 1950's National Town and Country. One of them is dead and needs a rewind. They sort of look like humbuckers at first but with they covers off the magnetic structure looks more like a mini Charlie Christian. They don't have much magnetic force. The good one shows that the coils are wound to a little more that 9K. I'll have to install these in the test guitar when there done to see what they sound like. Cool pickup!
