Teac 1/2 inch tape lifters maybe !!

I got a bit confused with some lifters that was lying in a box here donkeys years

These look like they have half inch wear but had only broken one half inch machine and i have the lifters for that, I may need to consign these to the " I dunno" bin but have put them here until I can find out what they really are, some are with springs some just the metal lifters

Compare with what you have there and see
