Here is a vintage 1950’s archtop guitar scrathplate. It is in very good condition for its age.
It fits archtops via 2 nails that go into the side of the fretboard, and 1 nail that goes into the bridge.
The third fitting position is the standard arm that screws to the side of the guitar.
You do not neccessarily need to fit it to the bridge.
It measures 10″ x 3 1/2″.
