My brother-in-law has an Old Model 357 Blackhawk he'll let me use this summer as we travel - but it's missing the rear sight blade. I THINK the rest of the rear sight is there, but the blade with the notch in it is gone. I'm at the library, using their internet. Figured I'd ask here first as I start trying to see who might have one. Thanks for any help in locating one.
