There is a final group of badges known as "National Park Service Associated Badges". These are usually a dual purpose badge, incorporating "Deputy Marshal", or some other law enforcement agency, along with a variation of "National Park Service" or "National Park Ranger", and occasionally the park name. Though not officially authorized by the National Park Service, badges of this nature were often purchased by the individual park, or the ranger himself for added authority.

Since there is no reference to these dual purpose badges in the official correspondence, nor manufacturer's marks on the back of those examined, it cannot be determined where, or when, they were made, or in most cases, used. Dating is equally difficult. Style is not a true indicator since the purchaser could have selected an old badge blank to have his new information applied. Most, though. appear to date from the earlier decades of the century.

Sequoia National Park Forest Ranger

This badge is the exception to the rule. It was probably worn by a ranger in Sequoia National Park prior to the separation of the Services in 1905, since after that date all rangers working within parks were known as Park Rangers. It is made of nickel-silver and has an ornate scroll-strap border in the shape of a stylized shield. In the center are three bars with a stippled background, of which the top and bottom bars are arched. The top bar contains the words FOREST RANGER, the middle bar, in two lines, SEQUOIA/NATIONAL PARK and across the bottom, CALIFORNIA. The pin on the back is of the safety pin variety, without safety latch. Size: 1-3/4" wide x 1-15/16" high.

Grand Canyon Constable

This is the only badge in this group with provenance. It was worn by Hubert Reginald "Bert" Lauson when he patrolled Bright Angel Trail for Coconino County, Arizona, prior it's transfer to the Federal Government in 1928. While not actually worn after the Trail became part of Grand Canyon National Park, it is included here because of the man that wore it.

Bert was born on 25 January, 1886. He first arrived at Grand Canyon in 1910 and fell in love with the area. After working in the mines and trying his hand at farming, he went to work for Coconino County in 1919 as caretaker and toll collector for the Trail. With the transfer in 1928, it looked like Bert was out of a job, and the Canyon. But he quickly corrected the matter by becoming a member of the ranger force on l January, 1929. After almost 24 years of exemplary service, in which time he refused offers of promotion that might take him away from his beloved Canyon, he died on 3 November, 1951, and is buried in the Grand Canyon Cemetery.

The badge is made of nickel-silver and slightly convex, with CONSTABLE/GRAND CANYON/ARIZ. in three lines. Constable and Ariz. are curved. There is also a small decoration between Constable and Grand Canyon. Size: 1-3/8" wide x 1-5/8" high.

Gettysburg National Military Park/ Assistant U.S. Marshal

At first glance, this badge appears to have been used in Glacier National Park (G.N.P.), but in fact was issued at Gettysburg prior to the park being transferred from the Army to the National Park Service. The badge is made of heavy gauge nickel-silver and slightly convex with nine unprotected points, the odd point down. Across the face in four lines are the words ASSISTANT/U.S./MARSHALL/G.N.P. in light blue enamel. The words are alternately 3/16" and 1/4". Size: 2-1/2" wide x 2-1/2" high.
