I found out more about my Rock Island 142. It weighs 73 pounds and is listed in the 1931 catalog. It was called a pipe vise and had a swivel base, but not like we are used to. The big bolt thru the bottom had a large wingnut which could be loosened to allow the vice to swivel.
Now that I know how old it is, I will not need shipping info. I am going to keep it.
later edit: Is there a separate thread for Vises?
In the 1934 catalog, it says this vise will accept pipes up to four inches! and is guaranteed for a year but will probably last a lifetime.
Quite an understatement. It looks like this vise will last several lifetimes.
