The Karhumäki Karhu 48B was a Finnish 1950s four-seat monoplane.
Development
[edit]The Veljekset Karhumäki O/Y company was formed in 1924 and initially focused on licensed manufacturing.[1] In 1948, the company designed and built a prototype of the Karhu 48, a high-wing four-seat monoplane of mixed construction. It featured a fabric-covered steel-tube fuselage and fabric-covered wooden wings. This was followed up in 1949 by a second prototype, the Karhu 48B.[2] A limited number were built, including several versions equipped with floats.
