I am new to the forum so please be patient while i try to figure this all out........I have found a bottle that apears to be a blob top. i am not an expect so i could be wrong...it has the letters G.A.P. 1881 embossed on it. i am going to try to add pictures so everyone who might be able to tell me a little more about the bottle can see it. This is a new hobby i found while i was scuba diving so i am new to the hobby. i am looking for where it was made, what kind of bottle it is, and how much it might be worth.........thank you all to who replys to my post......well seeing how the picture is to big i would be more than happy to photoshare the picture on yahoo instant messenger or email it to you thank you....matt3609@hotmail.com
