Attracting financial aid from a business friend with an interest in aviation, Martin turned to the design and manufacture of a small, two-seater touring aircraft bearing the same designation as the earlier project. Departing from the unconventional mid-engine configuration, the new aircraft was nonetheless, an example of an advanced design.

Construction involved a simple but highly ingenious method of using round section thin gauge steel tubing throughout the structure with a fabric covering. Powered by a neatly cowled six-cylinder inline 160 hp Napier Javelin

 engine driving a fixed pitch wooden propeller, the tubular mounting was designed so that all parts were accessible for easy servicing and was electrically started. A simple, tubular construction undercarriage carried low pressure tyres and employed shock absorber struts.

Martin believed that simplicity would lead to efficiency and took care to eliminate complicated operations, with the result that the prototype was rapidly put together by a small group of 12 semi-skilled workers. This design philosophy was carried throughout the simple structure with much forethought given to its cockpit and general layout. The wings were also designed to fold rearwards as a one-person operation, for ease of storage. Long triangular welded-aluminium

 fuel tanks, designed to be quickly detachable, were carried in the centre of each wing spar.

Although the main interest of this aircraft was in its design, a contemporary aeronautical journal reported: "The seats are comfortable and the cockpit is totally enclosed with an oval transparent hood. The windscreen is a sharp vee, with vertical front panes, which should not collect fine rain or snow and should obviate any reflection from internal or external lighting."

Testing and evaluation

Aerodynamically a straightforward design, when flight tested in April 1935, the MB1 (G-ADCS) reached a top speed of 125 mph and was found to possess pleasant flight characteristics which later became a hallmark of the Martin-Baker company designs.The Chief Test Pilot for the MB1 was Captain Baker.
