Barcalo specialty wrench

I figured this was another Ford model T related tool, but Google Lens tells me it was actually made for the Delco Light Co. of Dayton, Ohio, a manufacturer of gas-powered generator systems used to provide electricity to rural farms and homes during the first half of the last century.

The Grand Prix des Frontières

 The race at Chimay, Belgium was a road course and saw racing from 1926 through 1972. The 1951 event was a non-championship Formula 2 event and was won (for the second time) by Johnny Claes. Not much information to be found on the artist "Lomba".

Propeller for the Queen Mary

  One of four propellers destined for the liner Queen Mary. Each propeller was 20 feet in diameter, made of bronze and weighed 35 tons, poured in one shot, I presume... Those guys trust the rigging more than I do.
