Can you identify this Contraption on my friends Turntable Arm/Cartridge

[sparkyhx]

Someone I know is asking me if I can fix her (deceased Husbands) Turntable. She says it working loose. But I have NEVER seen anything like it. So I can investigate can anyone tell me what it is before I go up and am flummoxed?

Its on a Michell Girodec.

Thanks

Hi, it looks like some small "help tool" to set up azimut of cantilever against platter surface. I think Michell Gyrodeck on your picture has SME arm. This should be not so difficult to set up. BR.
