is what I'm looking for. I'm also getting the impression that between the original F1 (FL mount? no hot shoe/funky connectors around the rewind crank, ASA set by pulling up on the shutter speed dial) and the New F1, there were more than one variation. I've run across references to the F-1D, F-1N (numerous things documented as F-1Ns with various differences between them), and a handful of comemorative models.

Anyway... I'm flying my fighter down the trench... I see the two exhaust ports... I'm switching off my targeting computer... "Use film, Luke! Use film!"
