Schaller m/heads identity

[Dov65]

Seems an odd size this Schaller... 8mm shaft and the bushings just under 12mm, can't seem to find chrome replacements anybody came accross these before ?

M4 Schallers...must be an older version

Yep - have come across these. I think as you say they might be older ones with the 12mm bushing - I've got a set of these that I'm using on a build at the moment but they are used/vintage:

They seem to be more common with the screw lug in a different position with the 12mm bushing (I have an old Overwater bass that has this style fitted):

They do a new version of these but that has a 14mm bushing M4 90 (Light) | Machine Heads | Schaller Webshop
