Wow! beautiful. What good work. Not fair to call it gas pipe though. It's not 1010 .Raleigh was using harder steel on their brazed up frames than the welded frames had back then. It's more like 1028 carbon steel. I always felt the lower end lugged Raleighs had a nicer feel to them than the welded Schwinns and department store bikes. Now they were gas pipe.
