I spent a few hours fixing up this head today. I think in English it's called an angle head, but I'm not sure, I've also seen angular spindle head. Model is 2224. Toolholders are Morse Taper 1 collets threaded for an M6 drawbar.

The reason I started on it was to install a lifting eye. I've had it for a few months but haven't used it, partly because it is so heavy and awkward. The eyebolt should fix that.
When I opened the head I found it was full of grease (it should be lubricated with oil!) and the two angular adjustments were both stiff. After cleaning off the grease and fossilized oil, both adjustments work smoothly.
By the way, a great way to remove old oil from small parts, also known as varnish, is using foaming oven cleaning. Put part in a plastic container, spray liberally with oven cleaner, wait an hour. Then wash with an old toothbrush and water, dry with paper towels, spray with WD40. The oven cleaner is extremely alkaline so does not promote any rusting or corrosion.
If someone has an exploded diagram or parts list for this head, I'd appreciate getting a copy. The long vertical column contains the spindle bearings and gearing for the output shaft:

here is a view from the bottom looking up. The keyed drive shaft slides into the bore in the center of the bevel gear visible at the top.

Here is the head hanging from the lift eye, I got it pretty close to the balance point.

I drilled and tapped it M10 for the eye, and blew out the chips. I then radiused (concave) a short aluminum stub to be a reasonable fit on the curved top, attached it with epoxy to fill the remaining gap (circa 1mm) then milled the top flat.
Cheers,
Bruce
