I usually have a pretty good hand and mind for finessing my way into a camera but Im stumped on this part. The final piece before opening the right hand panel on a Topcoflex TLR is removing the winding knob. It has two small holes in the center button on the winding knob. I assumed that I would be able to use a small spanning wrench on these holes and the button would sink in, turn, and then pop out but I havent been able to turn it at all. I dont want to force it. I think this may be similar to a Rolliechord and Yashica. Anyone have any ideas?
