I have never heard of a Minolta 1,9/55 mm lens, but maybe someone else has.

They're a pretty obscure early MC standard lens, iirc.

So it looks like you've pulled the whole main element assembly off of the helicoid ring and have the main front elements out. But the element way at the bottom there you want to get out too? Is that what I'm seeing here? The image is looking at the front of the lens, correct? Do you have any more images of the disassembly? Are those chunks of glass I see there?

My first guess would be to try the spanner notches at 4 and 10 o'clock up at the top of the lens. I suspect that will unscrew as one all the way down to the element at the bottom. Something thin and rigid will do the job, like a butter knife, if you don't have a proper spanner.

Hey, yeah, this lens is very obscure but also cheap :-) which is why i bought it.
Yes i did pull apart everything the only thing that is left is that lens that you see, and i think there is another one just behind it. I have tried the spanner notches with a flat head screw driver, but it just wont budge, I've used all my force to try to turn it counter-clockwise but it won't move. but it does seem as if the only way to do it is through the front with the spanner notches, i just cant unscrew them! here are some more pictures of the piece.

Interesting, this one is a bit different from the other Minoltas I've had apart.

I see possibly a seam on the outside of the body. Have you tried just unscrewing the body apart at that seam?
