It was purchased by others out of the Gulf of Mexico,probably New Orleans around 1970. We have used it on many diving jobs and always kept it certified by our local department of Safety. Current certification good till may 2025.
We are in the middle of refurbishing it and putting it back into service for our own use. Sand blast and paint completed. New windows in stock. Some plumbing removed for painting not shown would be included.
