I need help locating the screws and nuts that secure the slip ring to the turntable base. The turntable is missing one screw and two nuts. See photos. Part numbers or a source would be appreciated.

Chances to find spares are minuscule unless you find another one where to extract spares. Germany (Märklin) has been using metric screws since before WW2 so you are dealing with standard screws (M2.5) or M2 probably . Not sure here but you can get metric scews at very small prices.

Some internet research revealed M part E755010 for the screw and E757010 for the appropriate nut. A few sources available, including at least one in the USA. The good news: this project is actually my "spare parts turntable." It has seen some rough handling in it's time, but I'm close to getting it completely functional. Pat

You can probably get both screws and nuts for very little money at one. Finding a good one will be your biggest challenge. You probably only need to match the length and thread and not the head type.

Certainly a less expensive option. I just hope I don't drop the existing screw and nut while I'm fumbling around looking for a match. Head size and type on the screw isn't critical underneath, but the nut and screw end need to sit flush in the slip ring to avoid interference with the turntable. Having confirmed size and availability of original fasteners, I'm calling this question answered. Pat
