Can anyone identify this phono cartridge?

Here are a couple of shots of a cartridge/needle I'm currently using in a Garrard RC-80. I love it for playing early LP's and 78's and seems to work equally well with both. I'd like to find a new needle for it, if possible, as this cartridge is quite good sounding with a GE preamp I'm using. I've not measured the output, but assume it is a magnetic or variable reluctance type cartridge. Any help would be greatly appreciated. Looks like two initials or a logo on the back and it does look like the front part with needle is removeable, but I haven't tried thinking I might damage it. If it ain't broke - don't fix it!

Those cartridges are Pickering. They were made in Oceanside, Long Island, and were one of tjhe best pickups to be had.

The styli in them were non-replaceable, and had to be sent to the factory for replacement. It appears that you have one 3 mil head and possibly one 1 mil head. You shouldn't guess what you have.

Upon inspection, you might find that the sylus in each one is actually OK. I have a couple of Pickerings, but use them only on making tapes, or special playings. They are very good pickups.

Thanks much for your reply and info. So I assume, then, that they are early magnetic units. The styli do not protrude much from the body, so a very little amount of dirt/dust clogs things up. There is actually only one cartridge with two different pictures. I thought maybe the needles were permanent. The early GE type in the Capeharts are also permanent soldered in place. Handle with care.
