A parade saddle set produced by Bohlin in the 1940s is the top lot of High Noon Western Americana's January 25 auction in Los Angeles.
It carries an estimate of $100,000-125,000.
It was previously owned by US attorney John Volz - the owner of Pine Trail Ranch, a horse riding school in Sacramento, California.
The saddle is crafted from black leather with silver and gold mountings that feature depictions of rodeo scenes. A sterling silver horn rises from the seat, topped with a gold Native American head.
Bohlin produced saddles for many of the luminaries of the American West, including John Wayne, Mae West and Hopalong Cassidy.
The example in the sale is identical to the one produced for Roy Rogers - a country and western singer and actor who appeared in a number of Westerns in the mid to late 20th century.
A Visalia Walker & Wegener loop-seat California saddle, circa 1890, is valued at $50,000-100,000.
The lot features the original strings alongside engraved silver conchos, buckles and spurs, and was presented to the grandfather of the consignor by a general in the California State Militia in the early 1900s.
It has previously been showcased in a 2004 edition of the Antiques Roadshow in Reno, Nevada, where it was valued at $16,000-22,000.
