Atlantic-Pacific Radio Supplies Co. was located at 648-50 Mission Street in San Francisco California. A-P was the sole distributor for the Oard Radio Laboratories line of receivers. Since all ads were made by A-P, we list A-P instead of Oard Radio Laboratories, Stockton, California.

The company was still listed in the November 1924, The Radio Trade Directory, under the heading manufacturers of Vacuum Tube Sets on page 82.

The Atlantic-Pacific Radio Supplies Company was incorporated on August 31^st, 1921, following the combination of two earlier companies: Atlantic Radio Supplies Co and Pacific Radio Supplies Co. The President of the new company was Henry B. Shaw, who was the former President of the Pacific Radio Supplies company.

The new company operated its tube manufacturing factory at 638-640 Mission Street, San Francisco, California and was under the control of Moorhead Laboratories Inc. In addition to this, the new company was instrumental in gaining distribution rights on the US Pacific coast for de Forest Radio Tel & Tel Co, Diamond State Fibre Co, Redmanol Chemical Products and the Shaw Insulator Company.  

The company exceeded its quota of tubes manufactured early in 1922 and RCA filed a suit with the court on April 24th of that year, suing Moorhead laboratories and the Atlantic-Pacific Radio Supplies Co for infringement of the Fleming patent. Also on May 9th, A.T & T. filed suit against Moorhead for infringement of the de Forest patents. All tube manufacture ceased on may 19th, with all tube workers being retrenched. Attempts were made by the lawyer, W F Williamson (a director of the company) to sell the business. This was unsuccessful and the company moved to 648 Mission Street (advertised in the San Farncisco Directory for 1923).

The company began a major change and rather than make radio tubes, began distributing radio equipment made by others. One of these was Oard Radio Laboratories of Stockton, (just outside San Francisco). Paul Oard was the owner of this company and they were the first clients of the revamped company. Oard made a series of radios in 1922 which had model numbers such as A-P 1, A-P 2 and A-P 5. They were also manufacturers of the famous Oard Phantom Radio Receptor. A name plate on these latter sets stated that Atlantic-Pacific Radio Supplies Co were sole agents for Oard radios. The Oard company equipment was in reality primarily distributed by thr Portable Wireless Telephone Company Inc, who consigned Oard products to Atlantic-Pacific.

Atlantic-Pacific Radio Supplies Co made a  US $ 250,000 stock issue for a planned expansion in 1923. The company had intended to increase their distribution of other radios and get involved with marketing general electrical equipment.Willis M Deming was President from May 11th, 1922 to May 9th, 1923.

The company ran into difficulties with the problem of not being able to make tubes and also the fall off of new clients. A name change was applied for on May 9^th,  1923 to Atlantic-Pacific Sales Company. An advertisement has been found on page 41 of "Radio" for September 1923. Occasional advertisements appeared in various magazines over the few following years. The plant and equipment of the old Moorhead Laboratories was moved next door to a warehouse at 650 Mission Street. (date not known)
