Propeller ID help

Came across this propeller listed for sale. Was advertised as being from a P-51. Talked with a member here who believes it's more likely from a P-63 because of the pitch settings and recommended I post it. The one photo got cut off but blade assembly is A-20-156-24M. Thank you for any info

Welcome to the site.

According to the 1945 list of props and governors the A-20-156-24M prop blade was used not only for the 11ft. propeller of the P-51K but also for the P-63A/C/D one of the same diameter. Judging by the Low and High angles there it better matches to the P-63.
