Hi ,
the seal will be the owner of the bottle,the best resources which I believe lists all known seals is ,"understanding Antique Bottles" by Roger Dumbrell, a huge though expensive book , but with all the information on antique bottles you will probably ever need ,another is "Antique Glass Bottles " By Willy Van Den Bossche ,the latest publication is a huge 3 volume work by David Burton "Antique sealed Bottles 1650-1900", again an expensive work and justifiably so with so much research and photography,
Bottles. unless full are not top of my interests so I don't have any of these books to hand to help you further ,
cheers ,
Peter.
ps the oxford bottles referred to with seals are for college rooms ie A C C R all souls common rooms
