I have a prewar 763E Hudson and have operated the more modern Hudsons (VL, ESE, etc). Obviously with the new ones you get more prototypical operation with slow speed and you get all the gadgets which I love. But still something about having that prewar engine that always makes me smile when I see it up on the shelf. The level of detail and work that went into it 80 years ago is something to be highly appreciated. And yes, it does take about 072 to run.
The only Hudsons I really know nothing about are the later 80s/early 90s versions but it sounds like they run similar to the older ones and may even be more fragile.
Great post! Always nice to read about a great engine.
