When your £10 punt on a camera doesn't pay off.

Took a chance on a £10 Petri 7s and in general the camera is in great condition, the meter seems to be accurate enough but the aperture blades are stuck.

At this price I may try to fix it.

Well I managed to fix the stuck aperture. A light bit of lighter fluid and opening and closing the blades has loosened the blade up nicely. What wasn't nice was braking the solder connection of the meter, very fiddly to re-solder. But glad to say it still seem accurate for a 70 year old meter.
