Lot of 7 dual cartridge carriers aka sled aka headshell. I'm not sure of exact models/versions, selling as a lot as is for tinkerers and collectors. I think there are 5x of one version, and two different other types. Some include untested cartridges. One has a P-mount adaptor bracket.

Note: I pulled the orig listing to remove one cartridge for a friend. I will leave this auction up.
