From a garage operation to building contest winning engines

In the 1930’s in Los Angeles, Henry Orwick experimented with 2-stroke, ignition model airplane engines made in his own garage. He continued into the 1940’s, when his .64 engine became popular enough that in 1945 production expanded beyond his garage shop to an address at 414 East First Street in Los Angeles. Although he had produced a .73 inch engine earlier and went on to make .23, .29 and .32 inch engines, the .64 turned out to be the most successful and enduring model. According to the instruction sheet that came with the Model 64, the price then was $32.50.

With the increase in popularity of glow plug engines, ignition engines were falling out of favor with the hobby market. Although Orwick did try a couple of .23 and .32 glow plug versions, the ignition engines remained their bread and butter until they went out of business in 1955. It is a testament to the faithful following Orick engines did have that years later another company offered “Reproduction” Orwick engines faithfully reproducing the original design. They are usually identified by a “K&M” marking on some of the parts and a serial number starting with “R” for “reproduction.” Dunhams in England also produced reproductions of the Orwick engine that were almost as faithful to the original design as the K&M versions.

The failure of the original Orwick engine business was due more to poor business practices than to anything actually wrong with the product. The original engines were never produced in very high numbers by production standards so remain quite collectible in today’s market.

The Model Engine Collector’s Journal ran a 7-part article on Orwick engines in 1999-2000, covering the period from 1937 to the company’s closing in 1955.
