Development

The Veljekset Karhumäki O/Y company had been formed in 1924 and concerned itself with licence manufacturing.[1] In 1948 the company designed and built a prototype of the Karhu 48, a high-wing four-seat monoplane of mixed construction, with a fabric-covered steel-tube fuselage and fabric-covered wooden wings. This was followed up in 1949 with a second example, the Karhu 48B.[2] A small number were built including a number on floats.
