>>6968331I have the 0.3mm PS-289, same body as the one in your image.
Its great, pretty much full compatibility with Iwata to a ridiculous extent. It basically is an Iwata HP-CH at a lower price. I tested out an Iwata nozzle on it, and it worked with no problems. The body is a bit longer than your typical Iwata, so you can use Iwata needles, but theyre just a bit too short for the needle stop to work. That whole head fluid system can actually be taken apart, which gives you some interesting options.
Take this for example, its a PS-270 fitted with the fluid head system from an Iwata Custom Micron and the .18mm needle.
