That one really is a true Beauty of the first Chop, and other than a protective layer of dust, seems in rather good nick there Nick!
I've always wanted one of those "bricked in" boiler type engines also, but I do have the remains of a Bing Monna that while not bricked in, does have a fully shrouded boiler, but it really isn't quite the same.
Wonderful engine you have there, helping to make that super long drive all the more worthwhile for you no doubt!
