I obtained this from the US on eBay about 15 years ago. The description at the time stated that it was a vintage Dynasonic pickup from the 1950s-60s. I bought it intending to install it in a Gretsch, but I hesitated to modify a vintage 1950s Gretsch with a single pickup, and it ended up unused. The wiring is as it was when I received it. Power and output have been confirmed.
