Default 1967 GTo Power Disc master cylinder question

I have a 1967 GTO/HO that has power disc (4piston) disc brakes. The build sheet shows that. When I bought the car, there was a master cylinder in he trunk that I was told was the original unit. The only markings are on the bottom of the piston housing. It is rectangular with a much larger front reservoir than what I thought was correct (no bleeder screws), oval dual with bleeders. The car is an early built 67 from Fremont pictures are below.

I should have put my question in the first post. Has anyone seen a master cylinder like this as original on a 67 power disc brake car? Being California built, there are a few parts that were different than 49 state cars, but I’m not sure about this master cylinder. Thanks.

I have not seen one like it on a 1967. It looks like a regular GM 1971-1980 disc brake master cylinder.

This is what I was thinking here....isn't the 67 master more oval shape with front and rear reservoirs the same size?

I show a 1 1/8 dia 5459784 bore stamped FR specific for a '67 Tempest (6 or 8) with disk brakes ONLY. I *thought* a 67 had equal sized cavities.
