Here's an unusual small radio strain from England incise marked "CLIMAX RADIO" (side 1) and Rd.No. 700718" (side 2). First one of these I've ever seen. 5 flaked ribs on side 1 and displays great on side 2. "Rd. No." is an abbreviation for Registered Number which is similar to the patent numbers used in USA. This identifies the insulator was made circa 1923.

First mail gets this scarce radio strain for only $35 postpaid. Thanks!
