P-Mount Cartridge ID Help?

[samrobertson]

Can anyone help identify either of these two P-Mount carts pictured below?

Not sure if the red stylus is intended for that cart or not - weird fit. Silver cart with black hood says made in Japan, so maybe an entry-level rebadged AT design?

The first cartridge is a moving iron design - the magnet above where the stylus should be is proof. So Nagaoka might be the maker.
I'm puzzled by the second one - that extra hole in the metal casing - what is it for? I have a Hitachi liner table (L 70, I think) with a cartridge that has a Pmount cartridge with an extra pair on contacts that energize and read(?) an LED so that the table can identify tracks. But that doesn't look like yours.

Sorry, but the second cartridge (w/ the red stylus) is not a p-mount.

Nagaoka seems like a very good guess, thank you. No idea what to make of the second, and can’t be sure if the included stylus is even intended for the cartridge. I wonder if it was supppsed to connect to a missing bracket a la empires and that could explain extra holes? No idea.

I’ve heard about those LED cartridges - mindblowing stuff.

Azden/Piezo were pretty fond of using stylus alignment holes in their carts, just like that second cart. The ADC PSX used them. Plus, mostly MI. Chuo Denshi uses that feature also.

The red one looks like a Chuo Denshi CN219 or Mg09d but missing the black plastic top of it.

Ah yes! I think you’ve nailed it. Somewhere I have another one or two of these lying around with the plastic top - will take a look and compare.

Not a fan of the MG09 but might see if I can track down a cheap stylus to sample the MI one.

Yeah - the hole in the top's significance suddenly occured to me - Hugo and Montycat are right. I have a couple of similar cartridges, but the metal casing is different.

Empire put their name on the IM cartridge above and called it the 105LT (conical) and 205LT (elliptical). Nagaoka and Nagatron (which I think of as US Nagaoka) sold a heavier-tracking standard-mount version. Nagaoka's was the MP-03 and Nagatron's was the IMS (Induced Magnet Systems) ME-1 (below). Finding any of these IM styli has, sadly, become very difficult.
