Here are some nice bottles found over the last few dives 

two of the dives were with Sean who was visiting from Boston.

The bottle neck on the right  is from the rare shaft & globe bottle 
c. 1650s, the free-blown green mallet bottle is from the 1730s,
the black glass 3 part Ricketts bottle (embossed on the base)
dates from the 1820s, all of the others date from the mid to
late 1800s. All beautiful additions to the collection!!
