Used from like '69 till '72, '73, originally for the 381...they look like hi-gains but have smaller polepieces (actually exposed screws, chopped down). These are on my 480. They are sick pickups!

Please excuse the brevity of the prior message (iPhone).
The easiest way is to look at the polepieces on the pickup. If they look like small round buttons with or without a hex head, they are later hi gains. If they look like small threaded screw tips protruding from the surface, they're transitional hi gains.
