I’ve been struggling to find a copy with unreservedly clean glass.

[edit] Prefer the later black seiko shutter

My lens is mounted in a Seikosha-S shutter. AFAIK there is no specific difference in the ergonomics.

So with the original Seikosha-S shutters you adjust the aperture with a tiny arrow at the bottom of the shutter and it basically necessitates looking at the shutter to make the adjustment.

The later Seiko shutters added a larger paddle that can be used and printing at the top of the lens to display the selected aperture.

It’s not a big deal, but if I can find one like that I’d choose that.
 
I understand your preference. I added a couple of photos to my listing. The aperture scale is visible on the top of the lens. The "tiny arrow" has a large paddle so you don't need to use a pencil to adjust it. The only difference is that the later Seiko shutters have a more easily visible shutter speed scale.
 

I see I see, interesting, that is much better than the aperture controls on the Seikosha-S shutters on the 90 and 150 I have. Hmmmmm
