It could be Japanese or East German to be honest, is there any info on the lens barrel ?
JayD said:Nothing whatsoever, lol. On the Prinzflex there is a "quality control" sticker, but it's so faded it's unreadable.
The Westron feels like a quality piece of kit, quite weighty and very smooth, but of course that doesn't mean the optics are any good.
Gold oval sticker? Probably Japanese version.
The Weston is made by Isco and is German.
