That looks the older style Taiwan built machine from the 80's. Great machine, I've got one just like it. A lot of times they don't get the respect that they deserve and seem to be looked at as a "round column step-child". I love mine and I've pushed it to do things that it really shouldn't do, but it takes it like a champ. I also have a Clausing 8520, and I use the Enco to do all of my "dirty work", like roughing and heavy fly cutting and face milling. I use the 8520 for more of the super accurate stuff and "finess" work. Congrats and good luck with your new toy. It will not disappoint.
If you want to see some of the potential enhancements to this style of mill, take a look at the YouTube channel "Cuppa Joe". He has done some impressive upgrades to his version of the mill he affectionately call "The Mighty Wrong Fu".
