Welcome Wifreid,
I think that Chester Model B is a combined Lathe and Milling machine.
(It may not be true, but I have heard that under heavy cuts, the mill head can move).
It is effectively the same machiine as the Machine Mart CL500M. If you want an operator manual and spare parts list, they are available on the internet.
If you cannot find them, send me a private message with an E mail address, and I will send all the stails that i have from my files.
Regards
Howard
