I wrote to Mossberg for information on the New Haven about a year ago. Maverick Arms responded to my inquiry and explained that the New Haven 600 was identical to a Mossberg 500. The New Haven was supposed to be an upgrade to the 500 and was introduced in 1977. The telephone number to Maverick Arms is 1-800-633-35565. They are the official service center for Mossbergs.
