Aircraft keep being repostioned while the museum continues to improve its collection and facilities, and this M-4P is one of them. Note the drip pans that seem to indicate there are still working components in this rare airplane.

The Tarpan was intended as a primary trainer but failed to meet the expected specs and costs, leading to the type's eventual cancellation. This example was donated to the super Polish Aviation Museum 1971 by the Mielec Aeroclub.
