The stylus (needle) is known as the N8-7D or S (D for diamond; S for Sapphire). The 7 indicates a .7 mil wide, stereo tip. For 78 RPM record players, it is a N8-3S, the 3 for a 3 mil tip.
There is also the N8-1S or D which is for early monaural 45s and LPs, which were the original, microgrooves. The 1 mil wide tips are a better fit or those.
Note that Stereo 45s, for the public, don't start until the later 1960s.
When buying these styli, you can also ask a seller for the "twisted cantilever, forked opening on one end" needle; the sellers will immediately know it....
More importantly, in the OP pic, that needle needs to be re-bent, in order to straddle the rubber piece, which modulates the cartridge "electrical" element.
Also, note that the shown needle tip is a Sapphire needle.
Sapphire needles are gentler to vinyl, as well as quieter with scratchy discs. However, Sapphire tips tend to wear after 15 hours of play...
So, playing a <3 minute 78 or 45, we can spin 20 discs per hour.
20×15=300 sides or plays !
That's a lot of spinning...
Dirty discs will accelerate wear on sapphire needles. Cleaning the discs and stylus, often, will increase usability and playing time.
Enjoy that UFO record player !
It's definitely from the "Jetsons" cartoon era...
