686 6" Rear Sight needed

[PattonTime]

I need a complete rear sight assembly for a older 686 6"
I would like it to be a white outline and it should be of the .146 height
These early ones had the front part squared off, not rounded like new ones
are.
Both Midway and Brownells are backordered I will try Smith & Wesson on
monday , but I assume they are too.
I would gladly take used , but new would be great too.
