Yes it is the Robart gear. Presently "sold out"on the Robart site. You might contact Robart and Sierra Giant Scale but my understanding is that Robart has exited the retract business for the most part except for what is left. . You might also try Ziroli plans. You could build your own set but would be a challenge.
Thinking about building one of these. Is that gear still available? Is that robart?
