excellent item, arrived in great shape and looks very good. arrived very quickly
Here is the cap for your 706A receiver made by Western Electric. These are usually chipped, rough or damaged. Now you can have a nice one. Don't use F1 caps. These are similar except the face is flattened more. Use the right cap 706A receivers were used on hotel wall phones and some payphones like the 161A. This is an exact copy of an original.
Nice cap, looks exactly the same as the original.
