Hojack,
Thats a great looking engine. Shades of The Blue Comet! I'm pleased to be able to assist. Nothing worse than a clockwork without a key. I felt that Owen was kind to make a key for the AF Hiawatha clockwork so I wanted to pay his generosity forward if any opportunity arose. My favorite Hafner engine is identical to David's but has a Lehigh Valley "John Wilkes" sort of scheme and it's somewhat similar to Overland Flier's engine. I electrified the yellow version.
