However, according to Polish Wings 22, Stratus 2017, The only Camel used by Polish Army was equipped with Bentley Vickers BR1 engine, morover during the crash aircraft was powered by a british propeller. Partial markings SO(P?)… remained may indicat in this case Sopwith Strutter aircraft (with 99% probability). The propeller was working with 9-cylinder rotary engine, Le Rhone 9J.
