Martin Finney 4mm scale kits


We now have available all 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.

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.
