Few more photos... still cant figure it out

The gun was in working condition before I tried to disassembled it. I did disassemble only the top part - to the point where I took the striker out and reassebled it. I did not took apart the handle.
As you can see.. it does not fit already when the top part - barrel-toggle - is separated.
