LENZ LPA 2S Boring & Facing Head

This is a vintage German-made tool for boring and facing in the mill, it's high quality manufacture but no longer made. Bought used off ebay I had to test if it worked quickly because parts are rather difficult to get hold of now and if it was faulty I had a narrow window in which to return it. I'll say now that I had no experience with this tool so I had to quickly learn how it functioned! Mistakes were made but I didn't break anything :). Turns out it is working fine despite its age, though some cosmetic defects (chewed up fasteners mostly) were addressed to satisfy my OCD. Here I describe the tool and demonstrate its operation.
