Well why would you invent something your not going to use? Kinda like the happy guy above, makes you wonder about natures jokes anyways.. LOL
Sure they made a MC carts. They just haven’t made one sense (since) the 60’s, Like I said a guy in Elk Grove CA repaired all the FM station stuff including his hand made carts. He was a Grado guy. The machine shop for Russco was in Antioch. Marchio’s Machine and Iron. I worked there. Just a tidbit..
I was at a guys storage in El Sobrante he was way up there too, over 1000sf of racks and TT. He had a Fairchild 750 with 12 & 16" platers I sure would have liked.
