Here's one for the books. Last night I watched the superb "Midwives" series that is so popular on PBS.
It's noted for the all-out effort they make to have only items
from the 40-50"s on their set. In last episode that had a shot of a 50's phonograph playing that had a braced tonearm which looked a LOT like what Rega is using now!
The tonearm itself was wide and tapered with a hole at the end that went over the spindle.
