Off the top of my head, it is the Owens-Illinois mark used from 1929-1956. If you show us the numbers around it, we can tell you the date more precisely.
Wheelah is correct, it is Owens/Illinois manufacture mark. They simplified it in the 50's so that is one of the marks I look for. Numbers to the left are plant numbers, numbers to the right imply date. There is a lot of good info out there on this company(myinsulators.com).

The '3' would indicate either that the bottle was produced at the Farimount, WV plant or that the bottle was produced in 1943. It's dependant upon where the '3' is located. Off to the left of the diamond means West Virginia and to the right indicating 1943.
Is there absolutely no other information on this bottle?
Does it say 'Duraglass'?
Now I'm curious...so please.
What is the brand and size of this bottle?
And, from where?
