saa hammer

I have an 1890 SAA revolver, but I am told I have a second gen hammer. Knurling is wrong, no line underneath. Also I am missing the ejector system entirely. Serial number is 130714. Pretty nice shape as a family treaure.

I picked up my 3rd Gen SAA and was contemplating changing the look of the silver-finished hammer... Were the 1st Gen hammers color case-hardened? I like the look of that on the hammer... But I was also wondering if any SAA hammers were ever blued to match the trigger? I've been trying to...
