I agree; it's not always easy finding these parts, and tracking down such quality examples as JoJo has for his projects is a difficult feat. I dunno how he does it, because a lot of his parts look to be NOS condition! Seldom seen for sale and when they do come available, it's always with an atmospheric price tag that pushes such items beyond the means of many.
However, there is also a great amount of effort, and attention to detail required by the hands assembling as well.
As someone who has been on both sides of that fence, I can appreciate what goes into a timepiece like this!
Fantastic to say the least...
