I am looking for a early 12 inch Columbia turntable with the taper mount spindle fitting.

There are several types of these turntables. Is it the thin, flat type that is cast iron with no holes? The next one has a thin rounded edge, with holes surrounding the rim. The most common one has holes all over like Swiss cheese. What machine is this for? That will narrow it down.

I believe the one with holes all over it like Swiss cheese is the correct one.
