Armstrong Bottle?

[JanieLee]

Ok so i found this glass bottle, its is very small pretty much medicine size. It has an A in a circl on the bottom and the marking 4DR. above the A and USA Below it, to the left of the A is -10- and to the right is 48. I have done some looking i think it may be Armstrong companys but im not sure. I cant find any that look quite like it ( not saying its once of a kind im sire its not ha) anyone mind telling me the meaning of the marks and its value if any ? Pictures Below

Welcome to the forum, they have no monetary value, sorry...

 

[JanieLee]

ok thats fine with me, would you perhaps know or care to tell me whats its for/ what the marks mean.

 

[epackage]

The marks could be mold marks for the style of bottle, location where it was made and/or the date of manufacture...

I meant a little more specific like does it say what year or the purpose im sorry i didnt specify, i've tried look all over the internet and i can seen to find any help but here.

@Janie

I'm new to all this stuff too. The SHA site that @epackage posted has really helped me. I've also fallen in love with http://www.glassbottlemarks.com/bottlemarks/ That site had the bottle marks for pretty much 95% of the bottles I've found so far. Lastly, I've had great success with using the advanced search function here on this forum. Like, I had a listerine bottle and I searched the forum for the phrase on the bottle. Found all the information on that particular bottle pretty much instantly!
