Recently I purchased a Burke and James 8x10" camera from a "reputable" online seller and when it arrived I immediately noticed a problem with the camera. It would appear that the teeth on the rear standard focusing knob do not properly contact the track on the bed, and instead are off by maybe 1/4" on either side. The gears on the focusing knob are driven on to a spline and it would be too narrow I think if a spacer were missing, but it would seem that something would have to be missing. The bed of the camera seems to have seen this problem for quite some time as a great deal of the paint is chipped and the wood exhibits signs of the gear having run all over it. Does anyone have any experience with these cameras or could you possibly show me the rear standard focusing mechanism on yours? Any help would be greatly appreciated as this is quite discouraging.
