'L' for 'Lewis', apparently. Interesting. The following site refers to MP 233: www.sizes.com/units/index.htm I also found two other documents. One relating to history and mentions the high status of handbook 44 and handbook 130 http://nvl.nist.gov/pub/nistpubs/sp958-lide/368-370.pdf It does not mention which of these two would take precedence. However, I get the impression that handbooks 44 and 130 might supercede MP233. Perhaps they are the current primary documents? I looked up handbook 44 2003 edition http://ts.nist.gov/ts/htdocs/230/235/h442003.htm Appendix C says that the US gallon is 231 cubic inches exactly. > Please let us know if you are able to obtain a copy of MP 233 from the > archives of the US Government Printing Office. It is a shame that MP233 is not online, but it looks like handbooks 44 and 130 might be what I am looking for. Does that sound right?
