Luxfer aluminum scuba tank. Manufactured in the mid-90s. Tank valve is not included. Made overseas, so the High-Pressure Gas Safety Institute logo is not stamped on it.

Please purchase only if you can pick up in Onna Village, Okinawa Prefecture. This is a used item, so no claims and no returns are accepted. Please message us before purchasing.
