Before and After
HRS's in their prime and not-so prime.
HRS-2, Bureau Number 130158 was delivered new to HMR-363 at MCAF Santa Ana in September, 1953. It went on to serve the Navy with HU-1 in Japan and back to the Marines with HMR-161 in Korea. In 1954 it was upgraded to HRS-3 standards and returned to Santa Ana, this time with HMR-362, and marked as How-Love 24. (ABOVE)
 
It served there until mid 1957. In the years to follow, it served both Marine and Navy units, was placed in temporary storage at Litchfield twice, and finished it's career with the Navy at Point Magu NAS. It was flown to NAS North Island in San Diego where it was Stricken From Inventory on September 5, 1967 with 3802 hours and scrapped. (BELOW)
Bureau Number 130160 like its sister ship (130158 above) was also delivered new to HMR-363 in September, 1953. It too, served numerous Marine and Navy squadrons throughout its career, last serving at Patuxent River NAS. It was Stricken From Inventory with 4508 total hours on August 23, 1968. Sold to the civilian market and registered as N7030, it has been a resident at the Atlanta Technical College's Aviation Department since 1969.  
HRS-2 Bureau Number 130167 was accepted on August 29, 1952. It was assigned to HMR-161 and given the squadron call-sign How-Roger 14. Less than two months later, on October 27, it was written off in an accident. What the Marines determined to be unsalvagable was sold to the civilian market and rebuilt by Orlando Helicopters. It is pictured below operating with Los Angeles Helicopter Airlines as N24111. The tail boom was replaced with the unit more commonly seen on USAF and Army S-55 variants which features a three degree downward slope . Additional windows were added in the cargo door and in the fuselage. The aircraft is still listed in the FAA registry in Grand Forks, South Dakota operating as a sprayer.
HRS-2, Bureau Number 130151 was delivered new to HMR-163 at MCAF Santa Ana, CA. on August 12, 1952. Through the years of its service it was assigned to many Marine and Navy squadrons in California, Hawaii, Japan, and Korea. Its last service was with HU-1 at Ream Field in 1963. In June of that year it was placed in storage at NAS Litchfield Park in Arizona. Three months later, on September 25, 1963, it was Stricken From Inventory. Sometime later, it was moved to storage at the AMARC facility at Davis-Monthan AFB where it was photographed by Sid Nanson in 1978 (LEFT).
Today it resides on display and fully restored as a USCG HO4S at the National Naval Aviation Museum in Pensacola, Florida. (BELOW)
