KoNickon, I did understand it was only in jest, and my "I'm not sure I am" was also in jest, although with the merest hint of the slightest possibility that there could be a microscopic chance that in theory maybe I am, considering most cameras on here seem to cost thousands with most owners having hundreds of them and hundreds of lenses and more photo talent than you could shake a stick at, and have the ability to make their own tools to work on cameras. On the other hand this place is more suitable for me than the USSRphotoforums of which I am a member, as I only have a Fed 3a(5) with an Industar 26m, most people there have hundreds of cameras and lenses and some could tell you what factory the official replacement screw for the bottom plate of the camera you're looking at came from, why it was needed and what the person who fitted it had for breakfast that day.
