Headshell connector on older turntables?

[GearNostalgia]

I have been looking at vintage turntables and wonder how I can figure out if the can be used with a new standard headshell that screws on. On this one it seems like the Yamaha GT2000 may have the same "screw" socket... is this an old standard? What is it called?

SME connector.

SME connector.

Thank you. Do you have any idea when this became standard?

These are meant to be pretty standard. I have one tonearm that doesn't work with the cheaper generic models, but they work with my other sme arms so it's more to do with the arm. I've cleaned the pins in the arm and exercised the springs so it should be OK, but it still doesn't connect with all my headshells. The pins in the headshells can sometimes be moved, I can't remember if I tried to adjust them. Generally shouldn't be a problem though.

Old thread. This connector type was actually invented by Ortofon. SME adopted it and so did many Japanese manufacturers.
I do not know when two guiding slots became common. Ortofon had one on the top for long (52mm) carts and one on the bottom for short (36 mm) carts so that overhang should not become wrong.
EMT used the same connector type with the connector pins twisted 45 degrees.
