I believe I have an SIP MP4. I say may have, because it has no model tag,
only the tag for the transmission speeds. Mine has 2 heads, one is Morse
taper #3 and the other is WW8mm watchmakers collet. I think it is a 1930s
model machine. Mine is in super condition. I oil the cups with STP motor
honey, which is like 600w steam cylinder oil. Reason being that it drips
so much, I figure heavier and sticker is better. I bought a MT#3 to ER40
collet adapter for it. Table travel is like 27" x 33".
I do not have a manual either. Would be interested in one also.
