I ran into incompatible threads on an old T/C Contender FP. The new target knobs refused to start in either the base or the aperture. The gib lock screw went in without complaint.

Anyone have this problem?

The very same target knobs went into a Williams FP for the Knight MK-85 FP-KN without a complaint.
