The Martin-Baker MB1 was the first original aircraft design built and flown by the company that later became more famous for ejection seats. It's a fairly run of the mill 1930s tourer in terms of looks and performance, but there are some neat design details including welded steel tube wings--even the ribs--that are worth a closer look. Check out this original FLIGHT article (three separate pages) to learn more. Cheers, Matthew
PS--The article was written in 1934, before the first flight of the one and only prototype in 1935, in case you were wondering about the dates.
