Thomas Berry Colby, ca. 1928

Thomas Berry Colby was born on May 15, 1900 in Detroit, Wayne County, Michigan. He was one of five children, having one sister and three brothers.  Born into privilege, he was educated at the Hill School, Pottstown, PA, and received his B.S. at Cornell University. Image, right, from Forden reference, left sidebar, chapter IV, page 80.

Colby landed five times at Tucson according to the following table.

At the times of his landings he was building his family business, Berry Brothers, which sold aircraft finishes – paints – and other coating products.  The business had been founded by his maternal grandfather.  Colby plunged into the enterprise after his graduation from Cornell.  

Although Berry Brothers sold coatings to the automobile and marine sectors, Colby chose to focus on the aviation business.  When he visited Tucson he was Aviation Sales Manager for the organization, having been appointed to the position in 1927. 

Though not a pilot at the time of his appointment, he talked the company into purchasing a Waco 10 (NC6528; ATC #41; not a Davis-Monthan airplane) and competed with it in the 1928 Ford Reliability Tour (Forden reference, left sidebar, chapter IV).  He hired Charles W. Meyers, then chief test pilot for Advance Aircraft Co. (makers of Waco planes) to fly the airplane.  Colby went along as passenger.  They took 4th place.

Finally, in 1928, he learned to fly at Culver City, CA.  He bought the Great Lakes airplane, NC840H and had it painted with the company name on the fuselage.  He was hailed in Detroit as the first sales manager to employ an airplane to cover his territory (but see “Pop” Cleveland and the information about the Parker Pen Company at NC126M).

He flew the Great Lakes on his first cross-country solo in 1929.  It is during this trip we find him at Tucson on November 12, 1929.  He wrecked the Great Lakes and bought the Monocoupe NC533W which he flew to Tucson twice in 1930.  Then he bought the Laird.

Colby flew in the 1931 (final) Ford Air Tour.  He did not compete.  Rather, he accompanied other Tour aircraft as the "Berryloid Official Tour Airplane", clearly an advertising and marketing gambit.  He carried as passenger Tour Manager Ray Collins.  He flew the Laird NC10402, below.  Image from Forden (left sidebar) chapter VII, page 140.

Tom Colby was active in flying events throughout the U.S. and especially the Midwest.  He was a founder and officer of the Aeronautical Activities Association of Michigan.  He was also pegged by the society pages as one of Detroit’s most eligible bachelors.  However, while participating in the Florida Air Cruise in 1933 he met one Juliette Brown of Philadelphia during the stop in Miami.  Two years later they were married.

The Berry Brothers’ coating systems were sold under the brand name “Berryloid” and were widely advertised and used in the aircraft industry of the time.  Many Davis-Monthan Register aircraft were painted with Berryloid, including NC14415 and, it is safe to assume, all of Colby’s airplanes.

Coating technologies have changed immensely (and for the better) over the years. Now, catalyzed epoxy and polyurethane finishes are available, which are far superior in appearance and durability (not to mention flammability qualities) to the nitrate dopes and lacquers of the Golden Age. Prices have changed, too. Whereas you could purchase a gallon of pigmented Berryloid for $8.35 in 1931, as of the revision dates of this web page, a gallon of catalyzed epoxy paint can cost over $100. Nitrate dopes have fared better, being in the range of 2-3 times more expensive today.

From dmairfield.org friend Tim Kalina come the following four images. The first is of the Berryloid pigmented dope color chart. This chart is circa 1940.

Older charts tend to contain more colors. The Berryloid chart below is from the early 1930s.

Given the charts above, and further to pigmented finishes in general, an article in the January 2008 issue of Skyways (cited in left sidebar) describes the line of Berryloid pigments, as well as a history of aircraft paints that includes reproductions of full-color charts for several manufacturers. Especially useful is author Eney's suggested procedures for determining the color schemes for old airplanes that may interest restorers or modelers.

This article is available for historical and educational purposes as a PDF download (1.1MB) here. The article contains black and white images of Lockheeds NC105N and NC869E. NC105N is rendered in color on the cover. A word of caution to modelers, restorers and all site visitors who may be looking for authentic color information: The color rendering of my scanner, combined with the color rendering of your monitor/printer, may not provide authentic colors for you to work from.

Below, an image of a promotional ink blotter that pictures the "Berryloid Waco" GXE 1103 (not a Davis-Monthan Register airplane). Named "On the Wings of Progress", this Waco won the NY to Spokane, WA Class B National Air Derby in 1927. The colors appear to be 'Diana Cream' on the wings, 'Renault Red' on the upper fuselage and 'Berry Red' on the fueslage sides and tailsurfaces. Thanks again to Tim.

An interesting and compelling artifact from the Golden Age is found on the business side of the blotter above. I've scanned it and exhibit it below. It appears to have been used once to blot the signature of one "Arthur Muehlbeck". You can see the results clearly. I increased the contrast and flipped the image horizontally so you can read the signature. Does anyone know anything about Arthur Muehlbeck?

For other print advertising, Berryloid produced a series of full-page spreads in the early 1930s that featured paintings of various aircraft types done up in bird paint schemes. These ads were also sold as a collection of prints. The mage, below, from Mr. Kalina, depicts the Boeing representative of the series (number 7). Compare the color chart, above. Number 4 of the series (a Travel Air monoplane in International Orange, Travel Air Blue and Vesta Yellow, suggesting a macaw) is reproduced on the back cover of the Skyways article cited above.

NC533W was delivered new with the Heywood starter. This model was activated by compressed air. Notice also the extension to the entry step just under the door. Colby ordered the extension for his wife.
