Purging old file drawers and found some 8x10 glossy prints. Based on the sharpness at 8x10 I believe they were taken with my B&J Press 4x5 in which case the lens was either an Ektar 127mm f/4.5 or a Kodak 152mm f/7.7. The '61 VW Beetle I acquired used in 1963.
Thanks guys! Actually I seem to have omitted that the shot was most likely taken in 1963, so the car wasn't all that old. Compared to my current anal-retentive record keeping, it's embarrassing how little record I have about stuff I shot in my teens and twenties. My slides usually have a process date and a written comment or two on the cardboard mounts, the rest, not so much. Live and learn --- well, live anyway.
