WWI Era Combined Logo Remington UMC 38 Winchester Ammo 38-40 WCF

This is a full box, 50 Mixed REM-UMC headstamped rounds, of .38 Winchester black powder ammunition (.38-40 WCF) manufactured by Remington UMC circa WWI time frame.  The two piece, round corner box has a near excellent green, red and black primary label with a very nice cartridge cut showing some age soiling and minor flaking.  The box is solid but is missing most of the side seal label.  The cartridges are all correctly headstamped with perhaps 40 native to the box and the balance having non-matching bullets and primers with some showing age darkening.
