Delivered to the US Navy as 122397 in 1949. Preserved at Pensacola from 1972.

On 6 April 1949 this AM-1 set an unofficial payload weight record for single engine piston a/c of 10,689 pounds. Over its short USN career it was assigned to Naval Air Training Units at St. Louis, MO. and NAS Atlanta, GA. After being stricken from use it was transferred to the Aberdeen Proving Ground in Maryland. Fortunately it wasn't used as a target and was transferred to the museum in early 1972. I took this slide not long after it had arrived and was in storage on the Naval Air Rework Facility ramp.

Preserved wearing circa 1947 markings of a USN Reserve Unit at NAS Atlanta.

Out of 151 Martin Maulers built, only 5 aiframes still exist. The National Museum of Naval Aviation displays one of the two restored so far.

In external storage awaiting the opening of the extended museum building at NAS Pensacola.
