Hotsell Canon Ccanonet

I have a Canonete QL17 G3 QL camera. Everything works as it should. It has a 40 mm 1.7 lens, a metal shade and a UV filter. The meter responds but is consistently 2 stops difference.This is because the difference in voltage between the original mercury battery and the alkaline replacement.I have taken this little gem and it has responded perfectly.The rangefinder is very clear and has a parallax box in the viewfinder makes it very easy to compose your shot. Just overrun with camera and presently trying to hotsell find a new home for this camera. Thanks for looking.
