Sand isn't going to hurt that stove any. Nothing special, just an old Grandpa (male if has 6 bricks across back, female if it has 5) Each stove has it's own personality, but I try to name the Mamas female and Papas male. Honey Bears, Baby Bears and Inserts are up for debate.
I do recondition some for friends, neighbors and family. I have a waiting list for Mama and Papas.
The key is 4 wheel dolly's, hand cart, ramp, levers and wheels. You should be able to drive hours for one and know you can load it yourself. Getting them OUT of unforeseen basements, soft yards, and stone driveways should be expected. Steps are the worst requiring help or a come-along cable for safety. I've blocked up stairs with 4 X 4s to support the extra weight and driven through lake effect snow to Buffalo. You will have a story about everyone you pick up, and sometimes it's owner. I've met quite a few original Fisher owners that shared their story buying and bringing their new stove home. Over the holiday, I called many I bought them from and am on a personal basis with some with an invite to return when in their area. When Bob said Welcome to the Fisher Stove family he wasn't kidding. I'm dealing with some original owners, dealers and distributers getting up in years, in poor health and making time to visit.
Satin Black is the closest to original and Stove Bright is the best paint. Rutland when on sale at Home Depot is fine for users. It's more flat after curing. You should fire them outside to cure, since transporting scrapes the soft uncured paint. I find Rustoleum BBQ Black to be the worst for dark pigment, drying a dark gray. The old originals were brushed, but you won't find any like that getting them from the east coast. Yours was done with high temp paint, just burned that hot. As long as it's not warped and all panels are flat, no harm done.
You need to read lots of threads using the search feature, as this thread you're on starts with draft cap info on post #4. (air damper as patented by Bob's father)
Here's a baffle thread to get you started;
