I've run 2 rolls of film through it and they both came out with the exposure looking great. The only potential issue is that the frame wobbled on both rolls (one was barely noticeable). The technician at Spectra pointed this out to me when I got the film back and said. it could either be because I loaded the film wrong or the gate needs an adjustment or lubrication. The only affect it has is that the border of the frame wobbles when playing back. The image is still centered on the film. If you crop in to hide the frame it's not noticiable. The serial number dates it to early 1940s (approximately 1941–1943). The little bottom plate shown in the photos without the handle is not included. The lenses are Angenieux Paris / Bell-Howell. One is a 75mm F2.5 and the other is a Retrofocus 10mm F1.8. Retrofocus means everything is in focus from about 2-3' to infinity! The camera is in amazing cosmetic condition for the age. Let me know if you have any questions.
