I collect patented stopper soda water bottles from Florida. I found a really nice WILLIAM HUDSON/PENSACOLA, FLA. aqua, tall lightning stopper. On the reverse is is embossed THIS BOTTLE TO BE RETURNED. I have seen one, maybe two of these but don't know if the price he is asking is reasonable for this bottle. Can a collector from that neck of the woods tell me how scarce this bottle is. It has no chips, cracks,dings or scratches on it just a little white staining that can be cleaned. Any help is appreciated. Thanks
