Shure Phono Cartridge 35-2643; Calrad CX-310, Herald or Audax Stylus Pressure

Description

For sale is your choice of phonograph part or instrument.   All were left behind in the electronics inventory of my late father, who was a radio and other electronics serviceman for most of his life.  He always kept a good inventory of new and used parts on hand, for quick service for his customers, for walk-in customers to his shop, who needed to buy a part, or for his own personal projects.   All were stored in a dry, smoke-free home.
Here's some information on what we have:
SHURE Crystal phono cartridge, part # 35-2643.  I find on line that this is also a Philco part number, and I find from the electronics blogs that this cartridge was found on at least the Philco D-10 changer.   It is clearly used, and has terminals on the ends.   I only imagine that my dad would not have put a broken cartridge in his inventory, but I can't test it and offer no guarantees.
GARRARD Pickup Stylus Pressure Gauge, Type SPG 2.   As is, as photographed.  It comes with instructions.  There is a tiny spring loose in the box.  I'm not sure if that is a part used in testing, or if it has come off the gauge.  It is untested.
HERALD Stylus pressure Gauge, Model X-671.  It comes as is, as photographed.  There are no instructions.  It appears to be in like-new condition.
AUDAX Stylus balance.  It is sold as is, as photographed.  It appears new, and the weights are there.  The instructions are on a cardboard in the bottom of the box.  I did find this in the Audio Craft catalog on line, 1958-02-OCR p. 46.  I clipped a photo of the ad, and included it with the photos.   The ad says that this is a precision instrument, with lab calibrated weights, it has no springs, so no inaccurately printed scales, and that this is the only way to obtain correct stylus pressure.

I hope that one or more of these phonograph items would be a nice addition to your restoration project, or to keep handy in YOUR inventory of phonograph tools.  I'll set the shipping up so that you are only charged for the first item, and any others that you might choose would ship for free!
Thanks for looking here!!
