Walt:
I'm glad to see you're still active as well. Unfortunatley, the old U.S.S. Brownwater was badly hogged and to be pulled onto the ways for repairs. Hopefully I'll have her afloat again soon.
The Baltimore project is very cool. I'd love to hear an audio clip of her while under way -- I've never heard the sound of a marine steam engine.
If you can recover any signal-related material from the Brownwater archive mentioned in Jim Martin's post, for use in the SCA site, please feel free to do so.
