Sorry no pics of during construction. I think the only bit that may have been of interest is in fiddling around trying to turn a standard 35mm lens into a usable focusing device for a completely different lens. I found it an attractive idea, although it required a fair bit of re-working, especially in forming a slot and maling a new slider for that slot that gave no play when focusing, and was tough enough to hold up with all the shutter cocking etc. I also found keeping the film and lens planes the same quite a challenge.
