I have just blown this up to 400% but 200% is best for the dates. I wonder who McQuade was but it looks like he lived from 1847 to 1934. He could have seen and just about fought in the Civil War and would have seen the First World War. The inventions of telephone, record players, cars, planes etc and still had time to celebrate the end of Prohibition and Al Capone! Who says life is moving faster nowadays.
PS I seriously doubt my ability to have read the dates at 200% if it had been 35mm. Great job on the camera. Take it along the the next LaMotta v Robinson fight. I've been waiting for the re-match!
