Hi, I was wondering if anyone could help me out, I have been cleaning out some things for my aunt and came across two of these guys... They are I think lens filters? With a 32 engraved on the side, so they are for some 32mm lens? I'm not very familiar with cameras and related equipment, especially old ones. These were in my grandmothers desk, so I'm not sure when they were made, but I'm thinking it was a while ago. The brand on the case is Cenei on one, Ce-Nei on the other. Can anyone give me some insight to what I have here? Any help would be appreciated!
