I just signed up with you. I have a question regarding the purchase I just made of 6 Standard Oil Quart Bottles in a wire rack. How can I tell if they are original bottles or repros?

If you post a pic it will be easier to get help

Most indian repo bottles have small metric openings ,if you have a original master spout,see if it fits,most repos come in 6 pcs, so,pics would really help,also bottle markings duraglass is spelt wrong on bottom lip,also Litchfield is spelt utchfield on metal spouts ,

What did they tell you when you bought it???
Fakes don't look old at all. Easy to tell even for a novice.
The wire rack is a give-away.
