A while back I acquired a camera engraved 'Pacer 35' in white lettering on a black body. I had no idea what it was, but a trawl of the net revealed that it was a re-badged Chinon, which is how I believe the GAF began life. The re-badging was for sale by the British chemist chain Boots, who used to sell a great deal of re-branded photographic goods at very attractive prices.
The camera was a complete heap - the battery had been in there for years and was a green lump and the meter cell leads had corroded through. This was in keeping with what I knew - that the previous owner had been into sailing. I had to make a new battery contact and bridge the missing sections of the cell leads. The rangefinder mask had become detached, but having sorted out these issues it cleaned up well and appears to work. I have a roll of film in it now so will see how that turns out.
