RARE Vintage Metal Tin Atlantic 6 Railroad Coal Miner's Lunchbox Pail

Description

RARE Vintage Metal Tin Atlantic 6 Railroad Coal Miner's Lunchbox Pail. I have had differing opinions on which one it was used for, and I guess it could have been either, or possibly another job. But pretty sure it is either coal mine, or railroad.
Has one spot down in the middle on the inside that looks like it has been repaired..like a hole has been spot welded or something..or fixed..but you cannot tell it from the outside bottom. The wooden handle has a worn place on it where you can tell it has been used, the thumb holding it has wore it down. Looks like a place for a thermos or cup to sit on top.
