I don't see any others using this mill. They were made in Los Angeles in the 50s and could be converted to Horizontal or vertical by changing the spindle. They came in a short or long table with a MT2 fixed quill and a true knee. Like all my tools, mods have been made. I bored out the quill to take MT3 collets to make more room than using endmill holders and it is powered with a GE industrial DC motor with KBIC drive. Mine is the long table (6" x 36") with the optional power feed on the left end of the table. It is on a factory stand set up for coolant which I seldom use because of the mess. Note the big WD40 spray container. The item on the right end of the table is a shop made spacer which indexes for 2,3,4,or 6 spaces. I can take the chuck of the lathe holding the workpiece and stick it on the spacer to quickly make flats.
