  The Karhumäki Karhu 48B was a Finnish 1950s four-seat monoplane.
  
  ## Development
  
  The Veljekset Karhumäki O/Y company had been formed in 1924 and concerned itself with licence manufacturing. 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. A small number were built including a number on floats.
