My grandfathers sidearm while a sheriff, in Rodeo New Mexico around 1920. The serial # on the 292xxx, a double action,4" barrel, nubers 289 on the frame. I dont know when the pearl handle was installed or?

I keep thinking a 1905 but all there is on the barrel is 32 W.C.F. . where the trigger guard starts to form on theleft side there is a triangle with what looks like VP.

What you have is a very late civilian New Army & Navy model, in the last frame type from late 1907 to early 1908, in 32-20 also known as 32 WCF (Winchester Center Fire). Nice looking gun with some great pearl stocks and even better family history.
The VP stands for Verified Proof. This was stamped on Colt guns after they were proof tested at the factory. This started around 1905.
