Problem with piston rings W108 280SE M130

Hello
I'am new user from Poland, so welcome everyone.
I have a problem with my M130 engine, 280SE from W108 1971 year.
I think, i have too big slit on my piston rings. It is about 1,85mm. I look for any information in my books, but I find nothing. Do You have information about this ? It's about 0,25mm ?
My piston ring "1".

usually , by the time you get there , there is a sizable amount of wear at top of cylinders , boring and new oversize pistons is the way to go . the ring gap looks too large , see if there is a difference at bottom of cylinder .
