Has anyone examined the new Ottoman range with a view to using them for earlier periods, particularly the 16th century? I am no expert on this but it looks like a very workable idea to me and I wondered if anyone with more specialist knowledge could offer their thoughts; preferably before the end of the month......

TheJanissaries and other infantry look useable. Never seen a representation of Renaissance Turk cavalry wearing those tall hats. You may want to look at mixing in particularly infantry with bow and various types of cavalry from the Saracen figures in the Crusades range. Also earlier Turkish heavy artillery tended to be on bombard style carriages with four wheels. A pity the armoured cavalry don't have a photo. You could try a Google search of images of C16th Turk or Ottoman armies and compare with the Baccus figures in the Saracen and Sudan ranges.

I'm putting a 17thC Ottoman army together at the moment. Would love to see a photo of the armoured cavalry. Earlier 16thC Janissaries would have the Matchlock Musket or bow and swords. So there are 3 options listed for these. Janissaries, however, did prefer hand to hand combat as this offered them the most kudos in battle. Azab infantry would have the Arquebus or bow. The Timariot and Qapu Khalqi Sipahis were heavy cavalry with bow and sword so use perhaps  CIS14 - Mameluke Cavalry, Bow - Armoured horses. Crimean Tartars I would use Hun horse archers. Bedouin light cavalry use the Bedouins from the Mahdist range. Djanbazan and Akincis light cavalry used bows, Deli and Kurd light cavalry used spears. Not sure as to what figures to use for these at the moment.

To be honest i haven't seen many references at all to ottoman turks with tall hats, neither during the renaissance, nor during the 1700's that these are supposed to be based on. But anyway.
I agree with the Timariot and Hun suggestions. For Delis i was thinking of using the CIS06 - Bedouin Light Cavalry
And for general Djanbazan and Akincis light cavalry I would use the a mix of the 
CIS04 - Seljuq Turk Light Cavalry - Gallop
CMA03 - Mahdist Cavalry 
maybe mix out the galliping spear wielders, to have just bow armed, although i think they were generally quite versatily armed and could melee, just preferred not to.
Same these three could be mixed,as they are all stood or waking.
CIS03 - Seljuq Turk Light Cavalry - Stood
CIS13 - Mameluke Cavalry, Bow
CIS11 - Mameluke Cavalry, Spear
