It is an "Electric" version with contacts for Practica cameras. The contacts serve no purpose on other cameras.I can see no marks on the glass and no fungus or significant dust, but there are two tiny white specks under the front element. Focus is very faintly gritty but this has no effect on focussing. Front and rear caps are included. Note: this is a vintage lens over 40 years old and there may be some small faults, marks or imperfections that I have not noticed and are not visible in the photos.
