The Webley & Scott No.1 Mk1 Flare Gun, introduced in April 1915 boasted a notable departure from convention - a robust steel barrel with a diameter of 1 ½ inches, contrasting with the more typical brass construction. This deviation in design was intentional, geared towards serving a critical role in the trenches and catering to the needs of the Royal Flying Corps.

Intriguingly, this flare gun shared a significant commonality with Webley's concurrent creation, the iconic MKVI service revolver. Nearly 50% of their component parts were interchangeable, reflecting a pragmatic approach to manufacturing during wartime.

The No. 1 Mark 1 Flare Pistol featured a substantial 10-inch barrel, underscoring its suitability for use in the challenging battlefield environments of World War I. Furthermore, it was equipped with a provision for a shoulder stock, adding to its versatility and aiding in precise aiming.

This particular model of flare pistol found extensive utility within the military. It served as a crucial means of communication, allowing messages to be relayed to artillery units and facilitating the signaling of orders to pilots soaring high above the battlefields. Its large bore and robust construction were essential features in ensuring the reliability of these vital communications.

Interestingly, the Webley & Scott No.1 Mk1 Flare Gun earned a unique place in pop culture history, as it was the basis for the weapon wielded by the renowned bounty hunter Boba Fett in the iconic Star Wars films "The Empire Strikes Back" and "Return of the Jedi." The flare gun's distinct and unmistakable appearance made it a standout choice for the character's weapon.
