...I have also moved the head off to one side and hung the part out past the table, clamped to the face of a right angle plate.  This adds a couple feet to the height of a part I can drill.  I prefer not to move the head around if I don't have to though.
The Clausing head can extend and swing like a Bridgeport, except for Nod. Tramming it square afterwards is difficult because the clamp screws shift the head when tightened, on mine the front and rear screws shift differently.
I position the spindle where an end mill will barely pass behind the fixed vise jaw.
A Clausing (Johansson) is similar to the original M head Bridgeport, which I've seen in this museum.

Bridgeports grew to a size and weight more suited to production while Clausings stayed light enough for wooden upper floors and 120V power. When I bought mine I disassembled it into pieces I could carry.
This is a currently available knee mill similar to the Clausing and M head, with R8 instead of their 1/2" 2MT or 7B&S collets:

I had the Enco version from the 1990's in my Mitre model shop. The main parts were well made, the minor ones were poorly fitted junk though salvageable. If you locate holes and cuts visually to scribed lines these more compact mills are easier on the back than a Bridgeport.
