Rear sight for pre-war I frame 22/32.

[Dvus]

I need a rear sight for a pre-war model 22/32. I obtained a beautiful 90% condition (except for the sights) pre-war 4" 22/32 this last weekend. The rear sight is missing parts, and I believe the remaining part modified for use as a sight. The front sight was replaced with an aluminum or stainless piece and filed down to work with the rear. I would love to find a front and rear set, but NEED the rear most of all.
