The "Princeton" was completed in due time and was equipped with two 12-inch wrought-iron guns, one brought by Ericsson from England and one designed and built under the direction of Captain Stockton.

Mr. C.S. Bushnell, who was instrumental in bringing Ericsson's plans actually before the Board, later associated with himself and Ericsson in the project two gentlemen of means, and large manufacturers of iron plate, Mr. John A. Griswold and Mr. John F. Winslow, who advanced most of the money needed, Mr. Bushnell supplying the remainder.

The project of building a vessel for the American Navy, the purpose which had most strongly attracted Ericsson to the United States, suffered long delay in connection with the arrangements between Captain Stockton and the naval authorities at Washington.
