I believe a good number are Mullers tournament knights, they should be those with MP on the base - Rick Sanders indicates this was Middle Ages Portrait figure per Mullers listings.
I think the standing figures with the lance are Maiers tournament figures, the others are new to me but, I bet the brain trust will identify them all.
(Muller figures are nicely listed in Rick Sanders wonderful book.). The Muller knights are beautifully engraved and paint up beautifully, Bistulfi’s site has some. Beautiful examples.
Nice acquisition.
