Can anyone tell me something about my grandfather's old 14k rose gold Mido Multifort? From comparing to other photos on this and related websites, it looks like an early one, perhaps from the 1930's? The photo files are too large for this site, but they can be accessed on DropBox at this link: https://www.dropbox.com/sh/hgl9f2ec7...iohPtE6Xa?dl=0
It works, but only for a few seconds at a time. Can something like this be restored? Is it worth it? How do I find someone who could work on it?
