Original Item: Only One Available. This full scale rubber replica non-firing prop gun as used in the 1898 Television Series Lonesome Dove. Lonesome Dove was a groundbreaking 1989 television Western miniseries that was based on the novel of the same name by Larry McMurtry. The miniseries, which was directed by Simon Wincer, starred Tommy Lee Jones and Robert Duvall. The miniseries would spawn several additional sequels, including 1993's Return To Lonesome Dove. A Colt Walker 1847 is carried by Augustus McCrae (Robert Duvall) throughout the four part film. This example was a solid rubber version used when he was riding horseback. It is offered in very good condition.

The rubber casting was made from a replica Colt Walker sold by the Replica Arms Co. which was originally located in El Paso, TX in the 1960s. They imported high quality Italian made replicas. This makes sense as finding an Original Colt Walker for the rubber casting would have been difficult, and is why this rubber prop is marked "Made in Italy" and "Replica Arms Co. El Paso, TX". This all rubber example was acquired from the Ellis Props and Graphics liquidation auction. Ellis was the oldest and the largest Prop House in California until its liquidation auctions in late 1999 and early 2000.

The Colt Walker, sometimes known as the Walker Colt, is a single-action revolver with a revolving cylinder holding six charges of black powder behind six bullets (typically .44 caliber lead balls). It was designed in 1846 as a collaboration between Captain Samuel Hamilton Walker and American firearms inventor Samuel Colt.

The 1847 Colt Walker was the most powerful handgun available up until the 1935 debut of the Smith and Wesson model 27, the very first .357 magnum chambering. The Colt Walker was created in the mid-1840s in a collaboration between Texas Ranger Captain Samuel Hamilton Walker (1817–1847) and American firearms inventor Samuel Colt (1814–62), building upon the earlier Colt Paterson design. Walker wanted a handgun that was extremely powerful at close range.

Samuel Walker carried two of his namesake revolvers in the Mexican–American War. He was killed in battle the same year his famous handgun was invented, 1847, shortly after he had received them. Only 1,100 of these guns were originally made, 1,000 as part of a military contract and an additional 100 for the civilian market, making original Colt Walker revolvers extremely rare and expensive to acquire. On October 9, 2008, one specimen that had been handed down from a Mexican War veteran was sold at auction for US $920,000  As reported in America's 1st Freedom magazine July 2018, a Model 1847 Colt Walker pistol - the only known surviving example complete with its original case, sold by Rock Island Auction for a record price of $1.84 million. This makes this the most expensive single firearm ever sold at auction.

The Republic of Texas had been the major purchaser of the early Paterson Holster Pistol (No. 5 model), a five shot cal .36 revolver, and Samuel Walker became familiar with it during his service as a Texas Ranger. In 1847, Walker was engaged in the Mexican–American War as a captain in the United States Mounted Rifles. He approached Colt, requesting a large revolver to replace the single-shot Model 1842 Percussion Pistols then in use. The desired .44-.45 caliber revolver would be carried in saddle mounted holsters. The Colt Walker was used in the Mexican–American War and on the Texas frontier.

Medical officer John "Rip" Ford took a special interest in the Walkers when they arrived at Veracruz. He obtained two examples for himself and is the primary source for information about their performance during the war and afterward. His observation that the revolver would carry as far and strike with the same or greater force than the .54 caliber Mississippi Rifle seems to have been based on a single observation of a Mexican soldier hit at a distance of well over one hundred yards. The Walker, unlike most succeeding martial pistols and revolvers, was a practical weapon out to about 100 yards.
