As far as I know it can also work on a M15 if fixed properly.

They intend to work of any of these models , the fact is to fix them and adjust them depending on the type

Was told that these come from a NOS collection which has been stored over years.

As stated, the head is not shiny anymore due to storage aging which does not affect in any

way the performance and sound of the Head.
