Well, I searched for this figuring I can't be the first person to ask. But had no luck. So, my apologies if this is a repeat.
I found a Sheraton this weekend and thought it was in shave-worthy condition (definitely not collectible). However, after checking it further at home, I find that one-half of one of the silo doors doesn't quite close all the way. But the other half of the same silo door does.
When I gently push down on the one-half, it does go down flush but it doesn't stay. And this effect is on the shaving edge of the silo door, too. You can see that the blade's edge would not be held snug against the comb, unless the silo door shut completely.
The silo door doesn't appear to be bent. The pins appear to be fine and working OK. It does open/close with a little difficulty (not much, but noticeable). None of the teeth on the combs (or any other part of the razor) appears bent or otherwise damaged.
So, has anyone else run into something similar? And found a way to fix it? Links, instructions and help are greatly appreciated.
