This is a very cool old bottle. I’m not totally sure what it is but I’m thinking it’s an old chemical bottle. My dad was a chemistry teacher and it was his. No chips or damage. It looks like maybe a stopper or a cork went it the top. There are measurements in ounces on the side. The bottle could use a cleaning. I am selling parts of a 50 year collection so please check out my other stuff that I have listed for sale. I have a lot of stuff to clear out. I will when possible combine shipping. Just let me know and I will do a refund if possible. I do not intend to make a profit off of shipping cost.
