Konica Lens 28mm f3.5 EE loose aperture level, small parts

[ts1000]

Hello,
I came across this lens (bought 'as-is' so not sending it back).

Discovered that aperture lever is loose, and and when moving aperture rink there seems to be some 'grinding' but not positive aperture clicks.

I decided to take a look inside, took off the metal ring, and then these 6 miniature pieces came out.
Seems like 2 springs, 2 metal balls, and 2 metal pins.

Where they are from, and how deeply would need to go disassembling it (I assume from the bottom) to get to the place where I can install them back?

The springs and balls are most likely from the aperture ring detent mechanism. Taking the lens apart until you can remove the aperture ring should reveal where they should go. Or, maybe not - advice worth price charged.

Following @Nicholas Lindan -> here is another lens showing the aperture ring locking mechanism with spring and a ball:

I actually didn't want this nice telephoto as a repair project, but rather as a problem-free access to my Tamron collection. But things turned out differently and I realized once again that every lens is designed differently. With this telephoto, which was highly praised for its imaging...
