These are pictures of a Messenger One that I have not converted to 10 meters. It was a very clean radio inside and only the outside was encrusted with years of grime. The smaller HC49 style crystals used in the Walkie Talkies work in place of the HC6 crystals and bad HC6 crystals provide a base that they can be soldered to and then plugged into the radio.
This is a picture of the Johnson Messenger metal microphone hanger. Its nothing more than a piece of steel wire bent in the shape above.
