from the 1st pictures thats what i found,i couldn't find any model with an r8 shank so i assumed that was modified by the previous owner, i couldn't find the bolt to release the shank when i saw a small space where i could see a silver solder so i had the brilliant i dea to cut exactly there expecting to find the famous left handed threading bolt but unfortunately i did not found it,but still i found that the shank its threaded on something but i don't know where and how,so im afraid if i try to screw or unscrew in order to release it im gonna break something since ni don't know what type of attachment is and the direction to unscrew it.can somebody help me to find out what type of connections is the one on the picture and how can be disassembled?
