That's interesting. Looks like it is original. The pre PCB looks like a Warwick, the wiring all looks original so maybe this was a custom order?
Mind you the Warwick Corvette standard I have is passive according to the Warwick documents that it came with and the serial number on the Warwick website also shows it as passive but it is most definitely active and all looks original so god only knows what goes on at the Warwick factory on a Friday lol...
