1960 "should have been" built by Higgins Inc. at New Orleans in 1952.
 
2081 was built by National Steel & Shipbuilding Co. at San Diego in 1954.
 
2092 we are not positive on, but its either one of those two yards, or John Matton of Cohoes, who did built a run of LT's in 1954, I know "2095" was a Matton tug.  And just for sake of discussion, 2089 was a Higgins hull.
