Merville wooden airplane propeller

Airplane propeller in glued laminated beech, stamped g. Merville billancourt on each side of the hub. The sides of the hub bear the engraved inscriptions sv - 4c ren 140cv type 745 n16279 on the flat side the date of approval: 26 4 54 followed by the number 16279. This propeller was to equip the stampe and vertongen sv-4, a biplane built in from 1937 and widely distributed after the second world war. The front side is stripped revealing the very beautiful wood work (the purists will scream...). Note a missing part on one of the blades, see photos. The creature measures 2m long.
