Straker-Squire 15 HP classic cars for sale

History of the Straker-Squire 15 HP

Straker-Squire emerged as a British marque in the early 20th century, initially known for their commercial and passenger vehicles. The 15 HP model typifies the pre-war engineering approach with a focus on mechanical durability and straightforward construction. Produced during a period of rapid innovation, the 15 HP was built in limited numbers, making surviving examples notable for their rarity. Straker-Squire vehicles commonly participated in early motoring events, helping to establish the brand’s reputation among enthusiast drivers of the period.

Model History of the 15 HP Series

The 15 HP was introduced as part of Straker-Squire’s push into the private motor car market. It did not directly succeed or precede a large family of models, reflecting the company’s diversified output and relatively short production runs. The 15 HP catered to middle-class buyers seeking reliable transport in the burgeoning age of personal automobiles. Its production was curtailed by the company’s focus shift during the First World War, when efforts moved to support military vehicle manufacturing.

Highlights of the Straker-Squire 15 HP

A standout feature of the 15 HP is its torquey, side-valve engine configuration, ensuring smooth operation at low speeds—an advantage in early-20th-century road conditions. The chassis construction employs robust, riveted steel, while the hand-built wooden body elements reflect the craftsmanship of the era. With only a microscopic share of existing pre-war British cars on today’s market attributed to this manufacturer code, owning a 15 HP is a distinct rarity.

Technical Data for the Straker-Squire 15 HP

Special Editions and Collectible Models

No officially documented special editions of the Straker-Squire 15 HP exist. Due to the bespoke nature of early vehicle production, individual cars might feature custom bodies or coachwork, potentially increasing their desirability among collectors.

Weak Spots and Common Issues

No manufacturer-specific weaknesses are documented for the Straker-Squire 15 HP. However, as with most vehicles from the Brass Era, expect challenges sourcing parts for the proprietary engine and transmission components. Wear in the timber body structure and metal fatigue in the chassis rivets require attention from experienced craftsmen. Period-correct repairs often demand bespoke fabrication and the involvement of specialists familiar with pre-1920s technology.

Engine, Transmission and Handling

The 15 HP was designed for usability on the primitive roads of its era. Its four-cylinder engine produces ample low-speed torque, while the heavy chassis and non-synchromesh gearbox mandate deliberate, skilled driving. Steering is direct yet weighty, and suspension is firm, reflecting the demands of early motoring. Braking capabilities are modest by modern standards, requiring careful anticipation in traffic.

Notable examples include coachbuilt tourers with lightweight open bodies—these configurations best showcase the vehicle's period performance and are of greatest interest to specialist collectors.

Interior, Comfort, Exterior and Design

The cabin reveals wood framing and leather-trimmed benches, while exterior design favours upright radiators and flared mudguards. Most 15 HPs feature brass detailing, including lamps, radiator surrounds, and controls, emphasising their vintage charm. Custom coachwork often led to unique colours and trim combinations, with accessories such as motoring trunks and custom hoods. Interior ergonomics cater to upright seating and high driving positions, suitable for visibility on unpaved roads.

Other Relevant Features

Some owners report modifications to improve reliability, including upgraded ignition and fuel systems. Original documents, if retained, significantly enhance historical value. Surviving examples often participate in heritage motoring events, underlining the enduring appeal among knowledgeable enthusiasts.

Summary

The Straker-Squire 15 HP is a striking example of Edwardian vehicle engineering. With its combination of distinctive mechanical features, hand-built construction, and historical significance, few British cars from this period can claim similar rarity on today’s market. Restoring and driving a 15 HP is an immersive way to experience early automotive development in Great Britain.
