Hello Nogoingback..
The Spindle looks to be a D1-4 and you have a good eye, the 3 jaw chuck is a Bison Set Tru 6 1/4" , the rest are not. and oddly there are 3 bolts holding that chuck to its back plate I think. I named it the frankenChuck because of that.
There is a bunch of tooling that came with the lathe, and several QCTP holders with bits installed... I have no idea whats worth keeping and whats not... some of it doesn't seem like its lathe tooling, or even go with a lathe. unfortunately there are no collets or collet closer
