In 1928 Allison Airplane Co built the Alco two-place high wing monoplane powered by a 60hp LeBlond 5D engine and priced at $2,385. Sold 1928-29 in plans or component form to the home-builders by Allison under the Alco label.
In DoC registers, samples of monoplanes constructed by individuals are [N321] with Anzani, [N149N] with Harley-Davidson, [N239K and N12577] with OX-5, [N982N] with Ford A, [N13618] with 60hp LeBlond—the OX-5 and LeBlond are a bit out of place, powerwise, and might be other models, such as MT-3. [N897H] was a biplane with 70hp Siemens-Halske, the registration of which was reportedly shared with Blatnik BD-1 for unexplained reasons.
