Lister D Is Almost Ready to Ship — Built Better Than Ever

Great news — the RETROL & OKMO D Type Stationary Engine Model (Lister D) is now entering its final production stage.

All orders are scheduled to ship no later than mid-April.

Even better, alongside the engine, a new solid-wheel chassis version will also be launching soon — giving you an even more authentic and robust display option.

We know many of you have been waiting patiently, and today we’d like to share what’s been happening behind the scenes — and why this wait will be worth it.

What’s Upgraded

✔ Metal Piston Ring Upgrade

The engine now features metal piston rings instead of the original sealing solution.
This upgrade provides:

• Better sealing performance
• Increased durability
• A more realistic mechanical experience

New: Solid-Wheel Chassis Version (Coming Soon)

To further enhance the overall look and mechanical authenticity, we are also introducing a solid-wheel chassis version.

Compared to the standard version, this new option offers:

• A more classic and industrial appearance
• A stronger visual presence
• A design closer to traditional stationary engine setups

Whether you're a collector or a mechanical enthusiast, this version brings even more character to your Lister D.

A Thank You Gift for Pre-Order Customers

To show our appreciation for your patience and support, all pre-order customers will receive a complimentary starter accessory pack, including:

• Water bucket
• Fuel funnel
• Fuel dropper (plastic bottle)

These practical tools are designed to make your first setup and operation easier and more enjoyable.

Worth the Wait

The Lister D is more than just a model — it’s a piece built for those who appreciate mechanical authenticity, hands-on experience, and lasting quality.

With upgraded internals and new display options, this final version represents our commitment to doing things right — even if it takes a little longer.

Thank you again for your patience and support.
We can’t wait for you to experience the Lister D.
