I've got a bag of about 80. They're loose devices, never soldered (the application used sockets) with a general smear of pigeon **** (heatsink paste) about them. Date code is 9540, the '80s ones I misremembered. (There was a production change around 1983 to devices with lower typical current gains). PM sent.
