Nearly 40 years ago I opened an independent record store.  I had literally thousands of phono needles in stock. I have recently pulled this NOS (new old stock) merchandise out of storage and am gradually listing some of the needles for sale. Rather than settling for cheap Chinese replacements or styli where you have no idea who made them, you can get actual vintage styli made by the original maker of your cartridge. This is a genuine ADC RSQ30, 31 stylus for the QLM30  and MK III Cartridge. Although it is in Pfanstiehl packaging it was made by Audio Dynamics Corporation as is printed on the back. This is old store stock.  You should be able to determine all the technical information you need from photo number 2, which is the backside of the package.   Please be aware that the packaging can show some wear, as they were in stocked in their little needle storage drawers for decades, and were handled and flipped through while in store stock. All are new old stock. FREE shipping in the USA. I ship these in BOXES and NOT in padded envelopes to help avoid any damage. Overseas bids are welcome but you will have to pay shipping.
