If I may jump in here, metengr has raised a point that I think needs clarification. Just because the plant was built in 1960 does not mean the "Code of Construction" was the 1960 Code; it may have been a prior version (depending on when the plant was designed).
To answer your direct question: My company has hard copies of all ASME Code versions, that were used to construct nuclear power plants in the US (and we're very protective of ensuring that we retain any version used). The earliest version that we have for B31.1 is 1955, but the next version is 1967. As a lot of the US nuclear power plants were built in the early 1960's, this would appear to indicate that there was not a "1960" version of B31.1; instead it was probably 1955.
Even so, I'm sure what you want to do is actually lay eyes on the Code, not just take someone on the Internet's word for it. (And I wouldn't have the authorization to send you a copy)
I would suggest first checking with your customer to see if they have a copy of the "Code of Contruction". If that doesn't work, I'd suggest a local library (or perhaps an Engineering School library). Also, you might try talking directly to ASME; I've always found them helpful. They would definitely be able to tell you the years that B31.1 was revised (i.e., is there a "1960 B31.1" or was the 1955 version the Code of Construction.
Finally, there are some websites that have been referenced in this forum that may have scanned and posted older versions of the Code.
