A couple of PBY5 were stricken back in 1942. I've found some props underwater close to shore at Argentia. Do you know were the serial numbers would be located on these propellers? I'll send pictures next week with measurements.
Thanks Sarg! these are some photos. I'll try to clean up the blades and hubs. Blade measures 62in top to hub. I'm a sailor not very knowledgeable about aircraft!
