I may be way off the mark but I believe I have a 1934 Hancock variant or a 1935 Hancock bezel with a 1934 movement. The strap also looks original with the writing "CALFSKIN" and "EXTRALONG" on either strap. Any further information is appreciated.
I am good with Cavalier as well, noting possibility of dial swap. This would be a first for the database, so we have none to compare to for dial verification. Based on ad Stephen found noting "same as Duncan" , it could refer to watch being identical except for case coloration (in which case it's a replaced dial), or same case shape with different coloration with the possibility of a different dial.

Thanks for helping me out with the identification.
