This weekends task was a fairly simple one, in the box of stuff there was a few old flash guns. 3 were still in there boxes and now work perfectly, 1 was loose and had some battery acid damage to the battery cover. This is a Sunpak auto 321 model and is quite compact but well jointed so it can be used to bounce the flash in just about any direction. This could be quite a useful tool as the other flashes are either really big or really small! so I set about trying to restore it.
