I have a set of new Rom Air retracts, complete with cylinders, valve, tank and even a manual punp. I purchased it in America's Hobby Center NY in 1982, for an Arrow project that was never build. Last year I got a new set of pressure tubing from Robart. I also got an OS 61 VF for the same project, which I never used either. If yor are still interested I can send you a picture.

Best regards.
