It's not a small lens, it's super tiny 
About half the size of small 1 inch C-mount lenses.
It's a decent lens too, did you try the adapter with aperture?
(18mm and 70mm are my favorite 110 lenses.)

Adjusted highlight, almost no PP:
no, i don't have other adapter than the cheapest from ebay.
i don't even though that this lens is usable. do you have link to the adapter with aperture?
also, i think placing the aperture near the rear might not be the same as inside the lens.
i forgot to mention: thanks to Stefan passing me his 110-set-of-four! thank you.

I don't think that aperture will make things much better - those lenses are almost at it's best wide open.
Actually I've tried but on my adapter it just introduced vignetting.

The Pentax 110 camera has the aperture at the back of the lens. it needs to be as close to the back of the lens as possible. Place the aperture further away and it will cause vignetting. A correctly placed aperture will help sharpen the edges up a lot.
