Jim, your the second person to show me a "crispy critter" so far THIS MONTH (a floor closer that is soo rusty you can hardly make out what series/brand it was) if it was one I seen and had to work on, probably give some effort to scrape off that rust and put some rust inhibitor on it and put it back in floor and put caulk or silicone seal along edge of box and put coverplate back on so it won't get any worse then it got.
I think the best looking old floor closer I have seen soo far was a Rixson #30 I spotted in a middle school I attended a play at today, that thing, someone must been thinking oddly or got bored and got investigating one day and they took off the coverplate (or lost the 4 screws) and applied wax to the floor (and left it that way for god knows how many years now!) not one speck of rust on it, with all the layers of floor polish and wax, I highly doubt it would be easy to turn the 2 valve adjustment screws. that school has been known to have lots of "naked" LCN 4040's losing their covers, and now the one floor closer?? LOL!
