The Margate sea defence diaries - identified earthenware shards No 1

Following on from my previous posting I am now going through the process of checking all the earthenware shards I found this year in Margate Harbour during the sea defence works.
This piece found in Margate Harbour is impressed with part of a word that contains the lettering "RWEILER". The complete bottle is either a ceramic gin bottle or a water bottle and dates from around the 1850's.The full lettering on the bottle would read GEORG KREUZBERG AHRWEILER RHENPREUSSEN and the origin is German.
