I didn't have a turkish drop spindle in my collection. That gap has now been filled. The timber is osage orange which is also used as a natural dye source.
I'm interested in thinking through the folk-engineering of my textile tools. The turkish spindle design is potentially easier to make at home than those that require a turned whorl--though I am yet to test that theory. Meanwhile it's going to take a little bit of getting used to as it handles a bit differently from the others I'm used to.
