Which time period does the Ottoman range cover? 

Ottoman army clothing didn't change that much from 16th to early 19th century, so you can use them for a wide range. The number of muskets should grow with the centuries, of course. But a lot of figures are still missing in the range, not only cavalry but infantry types as well.

I can't really add too much to the Ralf's answer.  The figures are very generic, but were designed with the 17thC in mind.   The missing cavalry will be addressed in the near future.
