Curious about this bottle? Decanter?

I was putting this in the yard sale box but the wear on the base made me curious. It looks like it has some age. It is very thick around the base. There is a yellow tinge to the glass but it does not glow under a black light. I see a scar on the base. No striation marks. It does not look like it was made for a ground stopper. Is it vintage or antique, EAPG or..? Thank you.

 

How many ounces?

It put me in mind of an old catsup bottle, but I didn't find a match.
I know I have seen these bottles before.

Somewhat similar but not quite.

Thank you for the link. I forgot to include the measurements. 9" tall an 3 1/2" wide at the base. It weights 20 ounces

 

Could also be an old vinegar bottle

 

I meant how many ounces does it hold.
But that doesn't matter now, as you say the base is only 3 1/2 inches. I would guess a condiment bottle of some kind.

Adding:
On second thought the shape might be more of a barber bottle shape with that wide base.

Sorry, I don't seem to be helping much.

 

Thank you for the picture of the vinegar bottle. I will look into those.

Cluttercloset, Actually you wer very helpful, it gives me a place to start looking. Thank you.

 

I found this auction Lot and has two of these bottles listed as Barber Shop Bottles.

I have found several now under barber/hair tonic bottles and the sellers state the dates anywhere from the 1920s to the 1950s.
