Product Information：
RETROL & OKMO L-D 100th Anniversary Edition is a 1/4 scale vintage stationary single-cylinder four-stroke gasoline engine model designed to commemorate classic agricultural power systems. Featuring a fully functional mechanical ignition system, the engine supports manual or drill-assisted starting and allows real-time observation of the four-stroke operating process. Constructed from precision-machined metal parts and mounted on a solid wooden base, the model presents authentic mechanical structure and balanced operation.
Centennial Tribute to a Classic Stationary Engine:
Created to commemorate a 100-year classic, this stationary engine design represents a historic starting point for fixed-engine enthusiasts. The model carries strong historical character and long-term collectible value.
Fully Functional Four-Stroke Operation:
The engine arrives pre-assembled and ready to run, featuring a mechanical ignition system. It supports manual start or electric drill start, allowing the four-stroke cycle to be observed clearly within minutes. The solid wooden base helps maintain stable operation during running.
All-Metal Construction with Vintage Craftsmanship:
Precision-machined metal components provide authentic mechanical weight and tactile feedback. The retro green surface finish enhances the classic appearance while helping maintain the engine’s visual condition over time.
Display-Grade Mechanical Collectible:
Designed for both operation and static display, the engine draws attention in studies, workshops, offices, or display cabinets. Its exposed mechanical structure makes it a natural conversation piece among engine, model, and industrial-history collectors.
Educational Mechanical Demonstration Value:
Besides visual appeal, the model offers a clear view into early internal combustion engine principles. The visible motion of the piston, crankshaft, and ignition system helps illustrate traditional stationary engine mechanics in an intuitive, hands-on way.

Product Introduction:
For many serious stationary engine enthusiasts, the year 2026 stands out as a milestone worth recording. Informed by extensive feedback from collectors, restorers, and model builders of antique engines, and developed as a dedicated tribute to an industrial mechanical classic from a century ago, this scaled model engine was introduced.
The story of the original engine began in 1926 with the sale of its first unit and continued until production concluded in 1964. During this period, more than 250,000 units were manufactured. Its development history reflects significant technical changes and refinements, including updates to the fuel tank, mechanical ignition system, flywheel, and exhaust layout. It also marked the early adoption of a 16 mm bore metal piston ring, representing an important structural advancement at the time.
Notably, a large number of stationary engine enthusiasts around the world began their interest in fixed engines with this design. This outwardly modest single-cylinder engine became an entry point into a wider mechanical field. The process of restoration and routine maintenance has continued to provide long-term engagement for enthusiasts at different stages, while hands-on operation offers a clear understanding of internal combustion principles and often leads toward more complex mechanical exploration.
To a casual observer, engines of this category may appear largely similar. In practice, each variation carries distinct mechanical characteristics—differences that are readily recognized within the stationary engine community.
