I did some more research, and it was the Dagor 100mm that Link used. It's something like f6.8 though. Hmmm. It takes a lot of flash power to light up a train using ISO 400 and f8. I only have about 10,000ws to play with. Link's flash power was virtually unlimited shooting those big flashbulbs! There's also a Dagor 120mm. I'll keep an eye out for one of those two. Another possibility is the Super Angulon 90mm f5.6. I think it's a newer lens, but it would give me a faster f5.6. That would be helpful. You guys know your stuff! I was aware that fast wide angles were pretty scarce in this time period.
