I am trying to figure out what collets are used by the highspeed head I purchased for my Schaublin 13 milling machine (1970's vintage)
The old catalogs say that it uses E collets which according to Regofix are the same as ER without the grove for extraction. I have one collet with the head and have provided a link to a drawing of it. The angles are approximate but shows it is clearly very much different from an ER collet which use 30 and 8 (front and back angles) and have a length of 31,5mm vs this one with approximately 25mm. The overall diameter is 19,75mm which I left off the drawing.
An ER20 nut will screw onto the spindle perfectly.

Any ideas?
