This is a high-end cartridge made by the American company Pickering, sold in the mid-1970s. The stylus is a Shibata stylus, and it was apparently for 4-channel playback, which was attracting attention at the time. The stylus seems to still have life left, and good sound could be reproduced (according to the seller's subjective assessment). However, the brush for removing dust beforehand is missing. Also, a compatible stylus seems to be available from JICO. This listing also includes a DAM entre shell.
