Mike:
Congratulations on a rare find!
When do you think this engine was built?
Hopefully, you will steam it and post a video for all to drool over.
Charlie
Thanks, Charlie!
I believe this engine was built in the early 1970s. I have another 55 with the original box that is dated 1975 and this engine is just a bit earlier, I believe.
A video will be forthcoming.
Thanks Mike. Very excited to see the video.
