This came to me a couple of days ago, with its original box and instructions. I know that these 1960ish Praktica's have been covered before a number of times, and that opinions about them vary. All I can say is, mine is totally unmarked, working 100% and the finder is bright and clear - once you remember to operate the film advance (which is by a bottom mounted lever although the knob on the top can also be used) to lower the mirror. One thing which puzzled me was that the bar which operates the aperture pin on the lens did not move forwards when I pressed the shutter, although a lever just behind it did move. It turns out that by moving across a little red dotted knob - seen in the second picture- you can disable the movement of the aperture bar when non automatic lenses are fitted. That brings me to the lens, a little E Ludwig Meritar 50mm F/2.9 with a pre-set 5 blade aperture. I didn't expect much from it when I mounted it on my Canon 7D and took some shots in my garden at F/11, after all, a 60 year old low end triplet couldn't possibly match an 18MP sensor --- or could it? That's it, thanks for looking.
