and C/O my brother, heres a couple of photo's of 1431 at Steam Inc.
The worlds first NZ120 blog. A mix of history of the scale, latest news and some modeling thrown in on the side. Poor spelling an added extra.
I started the weathering with tamiya smoke X19, which is a transparent colour. paint this on the roof and around the dirty bits. then i use a mix of tamiya smoke and water 50:50. wash over the whole model and then use a brush to soak up most of where the paint puddles. several coats of this builds up in the cracks and highlights the shadows, which no one in the larger scale does adequately anyway. its even more important in the smaller scales.

I've also heard that Colin Mcharg made available some of his loco zinc etches in 1:120 scale
At this point there were 2 groups actively modeling in the scale in Christchurch and Dunedin. however while the Dunedin group went for the modular approach with scratchbuilt models on commercial chassis, Chch opted for a set layout with modified commercial models, which they still had the cheek to call NZ120. The Chch layout stayed pretty much the same size, while the Dunedin layout grew to the monstrosity that I well remember. it was at this point i got involved with the Dunedin group. As i was a poor student, I scratchbuilt most of my wagons, and built a model of the railway station. To make extra money I would make models for the other guys in the group. this included assembling the first kits that I was aware of. someone in the club had done all the work to photoetch a dx and De, and we managed to get some done for us as well. I think there were 2 de's ( of which I assembled 1 on a minitrix H16-44 mech for a friend) and 6-8 Dx's ( of which I brought 2, and then built another 2) I also started casting models in resin, including za and Zp sides and ends, which i would then make up into complete wagons and sell. I also had a crack at making locomotive kits. This was a Df ( and i think the master for that is still in Darryls collection), which I made in 2 batches of 10, and these sold for the princely sum of $40. this made me enough money to go to conventions in Chch and still have money on the way home. I have no idea where these early models wound up.
that's about it for the early stuff. sorry there's no juicy bits/ falling out etc.
