The Type I mounting's were used on the Panther Ausf A and G, at some time during the production of the Ausf G the mounting's were changed to the Type 2, I do not know when.
Type 1 Mounting's

Prototype of Type 1 mounting.

Type 2 Mounting's. If anyone has more detailed pictures or know how these worked, I would appreciate the help.

Panther white metal parts already made.

If anyone has strong views on which mounting's I should make please let me know.
