Yes this has the round stud to fit in the round hole. Most if not all of these has the thin orange paint missing which happens from 40 years of exposure and if it is on there yet it chances are it won't be for long. All you need is a small bottle of testors paint or a ink or paint marker and it will look good. PM me if you interested.
I think so, one I'm needen has a round part on bottem that gos down in the round ho to lay flat, but I was hopeing to get one that steel had the orange paint, So I may think about it!
