Jim BielefeldtWhich balance staff for 992B
Hi Hi
I am currently looking at a watch for someone. Its a 992B that went through a washing machine. Its serial is C456717. The watch looks in incredible shape for what its been through and I can see little to no rust at all. The one place that is rusty , in fact rusted most of the way away is the balance staff. The hairspring is a nice shiny silvery colored one

. Can anyone help me figure out what staff this one needs?
Thanks in advance.
