The M1787 is a lighter and shorter version of the massive M1773. The basket was simplified and some of the brass bands were removed. The lead in the hilt was removed and the blade was shortened to 93 cm. I am not entirely sure if there ever was a production of the M1789 from scratch or if all the ones in existence are rebuilt M1773′s. The M1789 is one of the easiest dragonpallask’s to find and they should not ruin your budget completely.
