St Louis Hop Bitters

Another mystery in Aussie bitters is the reverse flag St Louis Hop Bitters. The moulds for these bottles were later re-plated and turned into Boston moulds. On some of the Boston's slug plates can clearly be seen on the shoulders and on the side of the bottle where the St Louis flag has been blanked out.

To my knowledge there are only 3 colored & 2 aqua ones from the semi cabin shaped mould, And only 2 aqua ones known in the more rounded shoulder shaped mould.
