It could be from a C-46 series aircraft, the blade model is 6491A-6, which a basic diameter of 15 feet, minus 6 inches to make the full propeller diameter of 14 feet 6 inches. So the blade would be expected to be about 89 inches/226 cm. From the picture it looks like the blade tip has been cut off.

Very interesting link.

According to Tech Order 03-20-1 dated 15 Sep 45 it was used on both the C-46 and the C-69. C-82 was not in service at that time so it is not listed in the TO.

Tom Feys link is excellent.
