What is this bottle with inner vial?

[Little Rock Bottle]

Trying to identify this for a friend--4" tall bottle with rubber cup on top and rubber insert holding a vial inside it. It comes in a wood holder/case also. All I can read of the bottom is B-D in the middle. Machine made for sure. Anyone know what this was for?thank you!Jill

Looks like an eye dropper to me...just guessing...

looks like a venereal cure to me , mercer or a bromide of some sort .1910 or 15.

So how would it be administered? The inner vial probably came out originally. Why have it fit down into the outer bottle? Or would I likely rather not know that?!

This is all very interesting in a gross way. I am responding only to see what turns up. I cannot imagine how and what it was used for. Jim

To me it looks like a bottle of something for injection. BD might be Becton Dickinson and CompanyI wish I could read it better.
