Thanks for the picture, I also stumbled upon it in my searches. I found a number of books on Ottoman dress -mostly in Turkish- but none of them with images
By kılıç I was referring to the sabre variant with the yelman widening at the tip. I had read a mention that yeniceri used a double-edged sabre, so this is the only Islamic saber I could think of that corresponds to this description. The variant without yelman are single-edged no?
From these images and from what I've read so far, I understand that yeniceri wore minimal armour/padding, and yet they were formidable adversaries. To fight successfully with little protection implies considerable skill - their schools obviously provided quality training. I wonder if any state records about the acemi oglan yeniceri school could shine some light on the existence of manuals...
