I recently purchased a brass oil bottle at a flea market for 5 $ and am wondering if i can get info on it

It has 2 numbers on it (identical) on the cover and the bottle. I presume it's a serial number or something. And it has wd engraved and a coronet with a 16 written under it. it's about 4 in long and has a diameter of 3/4"

Any info as to who made it would be greatly appreciated
