32 WCF parts gun

[fourb20]

I obtained a 5 screw 32 WCF revolver from local gun smith. He told me that the gun had been in a fire and he 'd only been able to use the frame which has the serial number C128096. He went through his parts bin and found a 32 barrel which has the serial number B73705 He found a cylinder in his shop that has the serial number 43323.
My question is what are the shipping dates of the three guns whose parts now make up one gun?

C128096 frame = 1950 (obviously a .38 caliber frame)

73705 barrel = c. 1916 or 1917
Note: the B is not part of the serial number; it only indicates a blue finish from the factory.

43323 cylinder = c. 1910
