My plan was to keep up my posts through vacation (and usually I have some done ahead of time), but that didn't happen. Things got hectic, Emily had a medical emergency, Laura lost her wedding rings in the ocean, and yet somehow we still had a great vacation.
Fortunately, Chris has been posting again, including some very helpful ones for when I get my ProtoThrottles.
In the meantime, here are three related photos, all flat cars loaded with engines at Pratt & Whitney. 3D printing folks, here's a new load for you to make!
Based on the notations on the shipping containers, it would appear they are these types of engines, built between 1944 and 1955.
