Wow that's really a great score of unique engines I'm glad to see they fell into good hands and they will be Restored and displayed rather than somebody throwing them in the trash and lost forever!!!
Thank you! As for restoring, a deep and thorough cleaning will apply to the 1940s #25G and I believe it is especially important to preserve the early #10 as is but cleaner since it is in such good original condition and will be a reference piece going forward.
