The lantern toolpost comment interested me enough to try googling when they were overtaken by QCTP's; even with several re-phrasings couldn't get anything close to an answer. The lantern/ rocker appear in lots of photos certainly later than WWII, but the next step were turret posts on engine lathes. My guess might be QC got rolling along with carbide inserts - still pre CNC.
All things considered, remain a great choice. The undeserved perspective being a hassle, is due just one factor. Few shops spent/ spend time prepping a supply of shims for setting tool height. Turrets are still quickest means to next tool, 4 usually sufficient. They also accept form tools or gang set-ups.
If I was to sit down and design an ultimate toolpost, wouldn't be QCTP alone; it would be 3 sides of turret and one of Dickson QC. I don't have a lantern anymore but know of shops keeping one around; because still the most compact, and flexible for unusual work, especially the 45° corner relief spec'ed in particular drawings.
Agreeing the photo has opportunistic staging; rolled up sleeves but wearing wristwatch. Between a watch and safety glasses, in my list of preparations the watch is first to go, for sure.
I do not feel one bit safer with eye protection unless turning brass, bronze or cast iron. My only eye incident ever, while wearing safety glasses and heavy turning with stream of short broken chips. The lens held one still blue hot against my eyelid until I slapped the glasses off, eye nearly fused shut about 10 days.
Later, when Mike Rowe declared "Safety Third" I was already aboard.
