Ebay find - Warrior Miniatures Spanish Cavalry

I was lucky to win a lot of 20 Warrior Spanish Hussars for a good price.  Eight of them are painted as Spanish (I think) and the remainder in black (early Prussians?).  So far I have touched up the Spanish, varnished them and based them to match my other figures. I should stress that the beautiful painting is NOT my work. Here they are:

The 12 black figures are just as nice and I will likely keep these as Prussians (if that's what they are) and add them to my small Prussian Warrior army.

Peninsular Warriors - Spanish Hussars

I have been painting these figures on and off for the last few weeks, a bit at a time. They are lovely figures, with loads of detail. They came on trotting horses, but I thought that their rather spirited poses deserved some galloping horses, so I orderd some from John Holt at Warrior miniatures. They came within a couple of days.

These guys look as if they mean business -

Spanish Lancers - Any Ideas?

I received these rather splendid fellows from John Holt at Warrior Miniatures and I am not sure how to paint them. They have rather curious looking headwear:

The only reference that looks anything like these figures is from a painting by Denis Dighton. The two fellows in the background:

Although the hats a slightly different, I will use these as the basis for painting, but would welcome any information that might help me with the uniforms.

Peninsular Warriors - Spanish Cuirassiers

Another heavy cavalry unit joins my Spanish forces, this time Cuirassiers in the splendid red tunics.  Also from Warior Miniatures, these lovely figures were fun to paint and look the part as they join the ranks of the Spanish Army.  I will need to send off to John Holt for some light cavalry next.
