Here is a double set of the great Swiss Knights produced by Reamsa of Spain in 54-60mm plastic.  These came out in the 60's and 70's as part of Reamsa's William Tell Peasants versus Swiss Nobles and Knights release.  This set features 2 of each of the Nobles and Men at Arms poses from this set.  They can be used either to expand your Swiss Army or to add additional knight poses to any 54-60mm medieval arrangement.  A great set to expand your armies or to use in making conversions.
