The VMS 20 and higher are very nice cartridges. The QL-F4 will surprise you when you remove the bottom cover. That is most of the weight of the table, light without it. Don’t forget to put 1/3 or less of a drop of oil on each of the shafts for the operating flippers. Gives the table a smooth, quality feel.
Hard to see the shape in the cartridge, but it is obvious it has the top channel. The stylus looks to be a later universal replacement as Ortofon stopped making different styli and moved to a single replacement.
Didn’t read the AI and Manfred posted while I was typing my first reply so I had to up my game and post that pic, but wondering if the AI knows any of what Manfred and I said about your cartridge?
