I got these series of pix which appears chronologically from my Tropas de Real Casa book which shows the alabarderos costume over the years.
Ignore the first pix which looks late medieval.
There appears to be two trends of uniform designs. The jacketed one (fig 2 and 4) and the checquered tabard one (fig 3 and 5).
Fig 4 has a caption of several Guard units including the Guardia Alemana (German Guard) made up of Germans who served Carlos V.
Fig 2 has a caption Alabardero. No further info. But this looks like the Landsknecht costume.
Google translate of the spanish text indicated that the German Guard dressed in the German fashion with white, red and yellow colours. Hence the "landsknecht" costume.
I think that in fig 4, the Guardia Alemana evolved into the fig 2 uniform.
Hence, the correct sequence for the Guardia Alemana uniform should be Fig 4 (jacketed, split colour with slashing), Fig 3 (no more split colour nor slashing) and then Fig 2.
Look at how the simple collar evolved into the fancier ruff collar, the flat cap into the top hat.
Looks like the Funcken illustration is based on an amalgam of fig 2, 3 and 4.
