1970s Japanese wrap around bridge Greco Les Paul Junior?

Description

A vintage chrome Japanese wrap around bridge I have always assumed might be off a 1970s Greco Les Paul Junior.  It has quite a lot of wear no breaks and does not come with saddles.  It does not come with mounting studs or any other hardware but has new post adjustment screws though.  The high E side post mount slot is narrower at the start, I could squeeze a 7mm diameter post through and it opens up to 7.5mm approx at the back.  The Low E side post mount slot is 7.9mm wide.

Bridge specs,

• Post spacing centre to centre = 81mm
• Post hole diameter = -7 – 7.5mm
• E to E string spacing = 50mm
• Saddle slots = 6.15mm bottom
