A rare WW1 period 'Apprentice Piece'  four blade mahogany aircraft propeller.
Showing the design of one of these fine early propellers - in miniature.

Most likely constructed by a cabinet maker from one of the companies who
produced full size examples during WW1, either to demonstrate skills, or as
a travelling sample.

There are no markings, but it has attained an excellent patina, including
drab green painted tips - these have 'crazed' confirming its age.

The blades measure 13.4"    34cm.
