Recent releases

GWR 3150 2-6-2T. This is a completely new kit to the highest possible standards. It represents the engines as rebuilt from 1919 onwards, with larger (deeper) bunkers, longer smokeboxes and superheated boilers.

This kit produces a complete finescale chassis in either EM or P4 for the Dapol GWR 43/53/63xx 2-6-0 model first released in late 2020. It only requires a locomotive body and a tender (which are available as spares) and not a complete Dapol locomotive.

Produced for us by Andy Vincent of Meon Valley Models, these are the best 4mm scale 3D-printed wagons that we have ever seen. They even have "readable" lettering on the axlebox covers!

The bodies have full interior detail on sides and floor and are designed to fit onto our etched brass sprung wagon underframes; axleboxes and buffers are included.

There are 14 types for Gloucester Railway Carriage & Wagon opens, in either 15ft, 16ft or 16ft 6in body lengths with side or end doors, inside strapping and with either 4, 5, 6 or 7 planks. Two Charles Roberts 16ft, two RCH 1923 7-plank and two RCH 1923 8-plank wagons and Midland Railway D299 and D351 opens are now available.

RCH 1923 Morton braked 9ft wooden solebar sub-frame. It is designed to fit under Slaters, Cambrian and Parkside wagons and includes finely detailed single-sided brakes activated from both sides. Newly released are for the RCH 1932 10ft Morton braked steel or wooden underframe wagons.

Other easy-to-assemble sprung sub-frames for the RCH 1907, RCH 1923 and Gloucester 9ft wheelbase Private Owner wagons are also available. All types incorporate springing as standard.

3-link couplings


We have sourced some very fine, pre-blackened chain which can be paired with our coupling hook etches to produce superb 3-link couplings (the chain is available in two types - scale and fine, and with either copper or iron links).

Martin Finney 4mm scale kits


We have available most of the former Martin Finney range of 4mm kits - six LSWR/SR locomotives and three tenders, fifteen GWR locomotives and three tenders, four LNER locomotives and four tenders and two LSWR van kits.

Please email us if you wish to buy any of these because we do not keep complete kits for all of these in stock and may have to pack a kit to order.







We have included many photographs of completed models and these take the form of thumbnail pictures which, when clicked, open out to full size photographs which can be viewed in (sometimes excruciating) close-up. Yes, these are 4mm models !!! We are incorporating more photographs in the form of a gallery for each loco and tender kit, and also pictures of the etches and extracts from the instruction drawings for many of our other products.
