Hi all,
Investigation finished

Museum commited error, badly recognized kind of engine
This no Pratt & Whitney R-1830 from „Liberator” !! No B-24 was not lost in Gulf of Danzig !
This engine this
Wright R-2600 „Cyclone” from plane
A-20G „Havoc” aviations of
Soviet Union Baltic Fleet. Most likely this plane one lost in March 1945.
Thank you all for engagement and help
Best regards,
Alkali
