Loose parts in Super Ikonta rangefinder

[Sam_PNW]

There were some loose parts rattling around in the rangefinder, so I opened it up and these two plates fell out. Fun fun... looks like one of them is supposed to be onto the top of the beam splitter prism on the left side, but I don’t see where the other one goes. The rangefinder works fine and is accurate, albeit rather dim. I’d like to fix these plates though, any help or photos available of where they might go is appreciated.
