LWS-6 Żubr
The LWS-6 Żubr (PZL.30, wisent) was a twin-engined medium bomber designed and produced by the Polish aircraft manufacturer LWS. It was only produced in limited numbers and was used for training purposes as it proved to be inferior to the contemporary PZL.37 Łoś medium bomber. The LWS-6 was originally designed as a 12-passenger airliner during the early 1930s, but was reconfigured to produce bomber instead.
