    I think it’s interesting that on Olympos website the S3 head (like Iwata) is more expensive.

    As they are produced in the same shop, I would not expect to see differences - other than those very subtle design specs asked for by the customer, Olympos, Iwata, Creos... Generally they vary in needle, nozzle, and exit orifice in the nozzle cap based on brand.

    it could be possible that the supply of S3 heads was one of the things they manufactured (or had manufactured) in the 2000's - supply costs would be from the day, and I am sure would have been higher than 2 decades earlier...

    Pictures of MP-200A with L3 head show it with stripes even though it is a .18 nozzle.

    I think the only way to really know is on the inside

    I can’t tell a difference between Iwata and S3 either.

    Edit: I meant the 3 stripes on Olympos head for L3. Not the air cap stripe to designate nozzle sizes.

    What I do notice is the Olympos.
    Need more pressure.
    But that is not in the headset.
    If I change them, it remains the same. I think it's in the airvalve. Or in the airbrush itself.

    I didn’t think of that being a factor. Interesting. I am going to check that out.

    Exactly, are there any olympos heads that are non L3 that have stripes?

    in terms of physical measurements, I find no appreciable differences in the air valves, or bodies of either brand. The air valve pins, seals, and valve body passages (at least among the samples I have on hand) are interchangeable.

    Yeah, That may just come down to the owner being very good at picking out price points based on popularity and supply.....or like dave said maybe they are of newer manufacture who knows.

    They claim on their website that prices reflect supply

    As the entire site is a marketing tool, I don't put too much meaning in anything they "claim" ;).

    This is the difference between Iwata V1 left.
    And the V2 right ..

    The headset from Olympos looks the same as the V2
    At first I thought that I mixt them but I have 2 that are the same as the V2.

    Is the vertical travel of the triggers the same?
    If so i would maybe guess the air air passage holes are slightly mis aligned on his particular brush where they meet at the 90deg intersection in the body?
    Something I've often seen even on high end stuff where two holes meet at a 90 and one is deep relative to it's diameter.
    Or it's brass from the 80s and simply has some minor corrosion deep in that passage.

    the air passages don't really meet at 90. There is basically a 45 or so off the top of the air valve through the hollow of the piece soldered to the front of the air valve, which then passes through the body near the front of the soldered on piece... I guess there may be a small 90 there... but, the vertical hole (which would 90 with the horizontal that carries forward to the head area) is @ two times the diameter. I would assume to help mitigate any misalignment's. Trigger parts are interchangeable. I use Olympos F-1 triggers on many of my Iwata's because of the shape, and height. The base is identical, as is the post - just the top pad varies.

    It should be remembered that the two brushes, Olympos and Iwata Micron, started out as a common brush. They were originally simply marketed by Iwata, then produced under license when Olympos stopped making new parts - or at least, stopped ordering new parts from the actual maker - refer to that whole "Fuso Seiki" thread ;). If one brush varies in any other way than nozzle, needle or air cap, it is most probably due to a particular age of manufacture, or some sort of an anomaly in one particular brush.

    Best as I can tell, the changes to the Iwata Micron that are designated as "V2" are all changes that had to do with manufacturing. The nozzle threads changed to a more standard size. The head base is pressed into the outer shell rather than soldered. The addition of the crown cap keeper to the back of the handle removed a through hole, so the needle is shorter. It also seems that they changed the shape of the nozzle to reduce the amount and length of taper on the needle, making it a stronger piece... The changes to the nozzle and needle are the only ones I can see that would have made a difference in actual performance.

    I meant the hole coming back from the head area as being "deep" but yeah I was just kinda throwing out ideas why one might vary slightly but I guess that vertical hole being double diameter would make it kind of hard to rotate the head base to a pinch point during production. That's informative.
    On the trigger I was thinking more along the lines of more coils or shallower slots in the body limiting downward movent slightly? Probably not but just a thought.
    Sounds most likely to me like minor corrosion in the holes, idk never cut an old airbrush apart but I have seen it in tiny brass carb tubes on NOS carbs. (New old stock not nitrous )

    anything is possible, I suppose... comparing what I have in front of me, and then reading about differences -I tend to lean toward some things being perceived vs. actual. That is, until I find samples that vary and explain the potential for differences.

    The air valve bodies, valve pins, springs, push pins, etc. - are identical among the samples I have on hand.

    I was on a different page. The Olympos 200 C has a different trigger style.
    And the airvalve is also different.
    They are not interchangeable.
