I received a tube radio console for christmas is there any one out there that can help me identify the make,model, and how some of the push buttons operate? The markings I have found are R.P.C. Chicago Serial #A 85183 and it has 3 bands shortwave, police, and broadcast and it has about a dozen push buttons under the glass dial? It works great would just like to learn more about it. Any help would be greatly appreciated.
