That looks like it, yes. However, the thread on the inside isn't the
same as the R-8 collets on my (Rockwell) lathe, it has, well, what looks
like a nut welded inside it for the equivalent of the drawbar. Maybe
nonstandard?

So buy or make a drawbar. All-thread rod works fine for this.
Use two nuts and a lock washer on the top.
