Hello Jim, the three figures from the page in L'Hoste's book "Armes Blanches Symbolisme Inscriptions" are commonly referred to as "Solingen Roses" and seem to appear on many Solingen produced blades between about 1780 and 1830.
There's a lot of variation in these and unfortunately the meaning of them is unknown. But my anicdotal observations suggests that they become less complex over time until they disappear.
You will recall we have discussed these in the past and I posted a thread about them here:
