To be more specific, the factory sent the wrong number of engines lettered Strasburg and Norfolk and Western. The only error was in the quantity not anything else. We found ourselves running out of one or the other, and we have since notified all affected customers, 6 of them. We have air shipped the subject engines back to the factory where I will personally supervise the re-lettering process. These models should be ready to ship out in 2 weeks. On a good note: Here is a video I took of the production model I tested before leaving for China.
