This would be mid-sixties and earlier, and I think I still have one among my massive archive of highly miscellaneous artifacts...! ...stevenc I recall reading that Jim Walsh* kept his cylinders in such a milk crate. Don Chichester * For those unfamiliar with the name, Jim Walsh wrote a monthly column in Hobbies magazine for several decades. I drive by his former house in Vinton, VA, at least once a week. I never met him, however, as he had died a few years before we moved to nearby Roanoke. ************************************** See what's free at http://www.aol.com.
