Murdock Loose Coupler for Crystal Radio

For auction without reserve is this Murdock Loose coupler inductor. Indicator consists of two coils arranged so the smaller coil slides in and out of the larger coil. Wood base for this unit measures 12 X 4 inches. Larger coil has a diameter of about 4 inches.

Smaller inside coil seems to have an extra screw. The head of the screw interferes with movement of the switch contacts. You can see the other end of the screw in the pictures showing the back of the inside inductor. I think this screw was added to hold the inside coil's back piece in place. This back piece does not seem to fit well and it also has a chip at the edge.

Larger stationary coil has a chipped area w the lower brass rod protrudes from the coil and a crack on the rear mounting foot.
