Yes, Philco called those cartridges their "dynamic" cartridge. They used them in their higher end 1946-47 and 1948 models. As far as I know they are the same as a mono magnetic cartridge, and they require a preamp circuit just like a magnetic cartridge.
Their drawback was the proprietary design for the stylus, which was a press fit. Too many cheapskates tried to press a steel 78 rpm needle into those cartridges, ruining them. Consequently, not many have survived, and of course the correct stylus is now virtually unobtainium.
I felt I was fortunate in finding that particular BSR for my client. I had not seen a BSR that used a magnetic cartridge prior to that.
