Minolta Autopak 8 D6 Dirt

[yader]

My Minolta Autopak 8 has some dirt inside the lens. You could see it in the viewer. I is not in the front or outside the viewer, it is inside. Is there any way that can be cleaned? Thanks for all your help.

Very interesting specimen! Maybe it's possible the dirt is somewhere along the path to the viewfinder and not in the lens. Like maybe the mirror which makes the corner to the prism. Whats it look like when you look into the lens from the front? Try shining a flashlight through the aperture while the camera runs.
