Teac 85-16 plastic counter lens if I remember correctly this

if I remember correctly this was used with tapes that had a pulse on to change the slides in projectors for big audio visual units and displays

There Is now a really big interest in these old Tascam Portasudios as they run at twice the normal cassette speed

The flap is probably what people want but would be same as all

Listed like this as people often buy the whole set so its a bit cheaper

This one is drawing 114mA  which on my scale would see it having some hours of service left

Teac 85-16 plastic counter lens if I remember correctly thisA very odd offering here , I came across this lens from an empty 85 16 shell, its only a piece of plastic but I have seen these burnt, broken etc
