I just noticed something that, in the end, made my Uma even more perfect. The button had been recessed a bit, making it below flush with the shirt. I had seen it being flush in photos of others' Poldi's, and I just figured mine was a little off. So, I finally decided to take it apart to have a look. After loosening both screws at each end the button popped out, perfectly flush. I think whoever assembled it did so with the button in the locked position, and that caused it to stay back a bit. It worked perfectly before and after. Anyway, now it looks even more gorgeous
Edit: Well, I wasn't all the way out of the woods yet. The button stuck again, slightly recessed as before. hmmm so it wasn't someone tightening the screws while the button was depressed in the locked position. What, then? After a fair amount of fiddling - sliding the side screw/pin back and forth in the slot, while disassembled, I found that it would catch if the silver pin was installed, but not if it was out. But why? Finally, on a really close inspection I noticed something irregular at the bottom of the slot, next to the silver pin hole. Using a paperclip end, I slid it along the bottom of the slot and out popped a small bit of metal shaving. Now it looks smooth and regular on both sides, so I reassemble the button and now it really is perfect. no really.. perfect
It's actually testimony about how precisely it's made. Just that little bit of metal caused it to hang up. There are minimal clearances, which is a very good thing. It's totally an honest oversight to miss the shaving. Seriously.. it was small and nearly invisible. This mod is definitely top quality. I don't think you'll find a better made one anywhere.
