Hi Celtan, the 1852 pattern had a basket guard. Like the British forces, the Germans did a reorganization of their military just prior to the end of the century. From an edged weapon standpoint, they simplified the patterns to broadly similar designs with just hilt decoration and regimental distinctions indicating which regiment and state the sword belonged to.
Gene's sword is a generic pattern battle sword that would have been used by all German States. 1852 pattern battle swords were recycled to Landweher (reserve) forces by the turn of the century. Many of the '52 pattern swords could be privately upgraded to have engraved blades, often with gilted or blued panels or damascus blades. The same is true for the M89 patterns as well although M89 swords with damascus blades are fairly rare. The M52, M89 and Gene's sword were meant for the ORs and NCOs while the Officers wore private purchase more ornate swords. These swords had important rank connotations as did the sword knots attached to them. Although they became almost jewelry for many NCOs and Officers, the private purchase swords could be bought with combat in mind. These types would have heavier blades.
I'm rambling now
so I'll just end with the comment that German swords are a fairly complex field of collecting. There are lots of swords to buy and atleast with Imperial sword fairly inexpensive. 3rd Reich stuff is a whole different kettle of fish and I never have collected there.
