If your looking for a prop you can fly with...there was a selectable pitch hub with replaceable blades availablein a recent model aircraft magazine ad. They had 2, 3 and 4 blade versions of the hub. Appearance was similar to the variable pitch props used on late 1930's to early 1950's aircraft. (almost perfect for a Corsair)

The only other useable in flight options are the common MA and Grish (and a couple of others...) props which won't look as scale, but using a rounded safety prop nut... its not bad.

For display only... most people make thier own.
