High performance bushing and seal applications for the General Aviation market are made exclusively for MBA by Thordon. Marsh Brothers which began as an aircraft and Helicopter Service organization at Hamilton Airport is the newest firm in the group and is applying products specially made for Aviation applications.

Marsh Brothers products are not made to OEM design but are engineered to provide longer life, grease-free service and lighter weight in critical airframe and landing gear applications. Products are sold as upgrade kits through select distributors or to overhaul shops to the General Aviation market. This business was built on an established base of successful warbird applications.


In 1970, G.A. (Sandy) Thomson launched a small film production company, using a 16 mm Bolex camera. His activities were then a hobby, until a respected educationalist inspired Sandy to make the company a commercial venture.

A film shot aboard a lake steamer, on its way to being cut up for scrap, was screened to steam engine enthusiasts, whose positive response and support led to their funding two additional productions.

Several industrial and commercial productions followed including CANUSA, (tracking annual athletic competition between the cities of Flint, Michigan and Hamilton, Ontario) and a corporate film for Canada's largest home electronics equipment company.

In contrast, THE EYES OF MEMORY was produced for the city of Burlington, Ontario to celebrate their 100th birthday. It provided a nostalgic look at a century of history and development. In 1980 the business was shuttered until 2004 when production resumed with the shooting of a one hour documentary film, THE MIRACLE OF KA114. After nine years in production this story about the restoration of a Canadian warplane in NewZealand is now being released for international distribution. Since 2004 many shorter films have been produced to showcase the parent¹s products and they can be viewed on the Thordon website.

The latest addition to the Cinema 16 collection of films is BERWICK AND THE BEACH CANAL, a film that advocates the efforts to restore and preserve that Burlington Canal Lighthouse in Hamilton, Ontario.  This lighthouse is historically significant to the community and also has ancestral roots to Sandy Thomson himself.  The film can be viewed on the Cinema16 site here or in HD on YouTube here.

This company was built from the ground up in Slupsk Poland in 2011-12 and began operating in 2013. Slupsk is close to the Baltic Sea about half way between Szczecin and Gdansk. The factory is capable of making all Thordon products as a back up to the Burlington plant in case of any situation where Canadian production might be interrupted.
