I bought this rather sad looking Selfix 820 last weekend! Its primary problem is that 2 pins are missing which should be fitted to the forward part of the chromed struts at the holes visible, and engage in the L-shaped slots so that the lens erects properly. Can someone with a similar camera describe what the pins should look like? Are they a plain pin, or mushroom headed? Is there any obvious sign of how they are attached to the struts? The holes are plain, not threaded, so I'd guess they must be riveted/peened in place, though they can't protrude above the outer surface or they would catch on the upper part of the strut when folded. Also, does anyone know how to remove the lens/shutter unit from the lens board? Viewed from the back there is what could be a retaining ring in the usual place around the rear element, but there are no slots or holes for a spanner, and it is very much obscured by the forward fold of the bellows. Steve.
