IJ Supershot Sealed Eight Rear Sight

[jmdavis984]

I recieved a second model Iver Johnson Supershot Sealed Eight (I'm guessing 1952-1954 because of the barrel) from my late grandfather. It is missing the rear sight. Some quick research tells me there are at least two rear sights on the second model SSS8, a solid blade on the 88 and an adjustable blade on the 833 and 834. Can anyone tell me if both of the sights will work on any of the revolvers, or are they model specific? If it helps, my serial number is L44638. I can include pictures too if that helps. Thanks for the help!

Does anyone know how to get ahold of Bob's Gun Shop (www.gun-parts.com)? I am not getting an answer to e-mails, and the site doesn't list a phone number. He is the last parts source I can find online that might have this rear sight. Numrich and Jack First don't have it. After that I suppose I have to start hitting up local gun shows.
