    Help identify these lens mounts

    I rencently picked up a couple lenses at a yard-sale, but I'm having trouble identifying the mount on one of them.

    I'm fairly certain the one on the left is a M42 screw mount, but I'm having trouble identifying the one on the right. The threads are identical to the M42, but in additiona to the little pin, it also has 2 other rectangular solid pieces on the edge - one of which is longer than the other. Any help identifying these? See links below.. thanks!

    Re: Help identify these lens mounts

    Looks like third party lenses for a screw mount Ashia Pentax SLR camera late/early 1960/1970's. There are a few other cameras they could be.

    Nikon D800, 50mm F1.4D AF, 16-35mm, 28-200mm & 70-300mm
