A simple question......which shows my lack of knowledge on this topic....Are these haube screw posts and nuts Metric ?

At that time both, inches and metric systems, have been used for screws and nuts. I always check the diameter, and if a thread has an unusual diameter in the metric, it was an inch thread. But it were mostly inch threads.
