Jack Identification

[dlevy]

Hi All,

Can anyone help me to identify this jack?

It was suggested that it is not a true AA jack because it does not have the oval cut out windows on the sides.

Any input appreciated.

Thanks,
Dave

Interesting. Everything I see shows the window on screw. Standards show two versions, later a little heavier with larger screw. I have two jacks, not sure if either is correct, but they both have windows.
