You lucky devil!
The number 085660 is probably the production serial number of the stylus, but that means something only to Shure. There were a number of different styli which were used on the V15 Type V body. According to Shure, the following colours were used on their V15 Type V styli:
- VN5G (spherical tip – this was only manufactured for a few years, so is probably hard to find now): red serial number on silver label; silver SHURE on black background
- VN5HE (hyper-elliptical line contact tip): black serial number on silver label; silver SHURE on black background
- VN5MR (Micro-Ridge tip): silver SHURE on bronze background. All 3 of my VN5MR's, bought in 2003 and 2005, say VN5MR in silver on the front above the stylus cantilever, and on the front of the brush say SHURE in silver (the 'bronze' colour of the background looks more like grey to me, and I'm not colour blind, having passed a lot of opttical tests for that), but there are no serial numbers anywhere on them.
Also, the following genuine Shure styli, which were from cartridges based on the V15 Type V-MR, can be used (they occasionally show up on Ebay):
- VNSE5MR (from Ultra VST-V): Similar to VN5MR/VN5HE/VN5G in moving mass (0.17mg), but a slightly higher optimum tracking force of 1.2g, and very similar performance and sound
- Ultra 500S (from Ultra 500): Dark brown with gray Shure italic lettering. Slightly higher tracking force of 1.2g, and even lower moving mass (0.165mg) and better trackability, so this is a slight upgrade from the VN5MR. The Ultra 500 was Shure’s best-ever cartridge, with ruler flat frequency response - the best I've ever seen in a review of a MM.
Note that the Ultra 500 and Ultra VST-V both have the same electrical specifications as the V15 Type V, so the sound is very similar.
That Jico SAS stylus is the best aftermarket stylus available for them - SAS is Jico's name for a Micro-Ridge tip.
I generally use Shure's stylus brush (it came with an M97xE) on mine, but the old Discwasher stylus brush I own is also good.There are probably a few available from suppliers like LPGear, which are similar, such as this one

If a liquid cleaner is needed occasionally I use some Nagaoka stuff I bought years ago, but this stuff from AT should also be good
