Those rivets don't look factory to me. They look like somebody put them on later for some reason, like maybe they come off, or broke off. It seems odd to me that Griswold would make a nice smooth lid and then drill two holes in it and put a cheap rivet in it. It just does not add up. I say this because if you look at Griswold products they are nicely made, good workmanship, smooth lines, and made to last. It just doesn't make sense that a handle would be attached in this manner, based upon the quality of workmanship that I have come to know with Griswold. I have a drill, I have a rivet gun, I could put handles on like this, and so could most anybody else. Of course this is just my opinion, as a lot of our comments are.
