I'm looking at c.€45 per kit. The chassis will be a hollow folded brass construction to match the prototype, brass etched detailing (handrails, hooks, screwlink couplings etc.) and the main tanker itself will be a brass tube with resin endcaps. Decals will of course be included. The bogies will be folded brass with brass axle bearings and whitemetal detailing to ensure smooth, true running. The bachmann Y25s are just too narrow under the bogie to be really suitable (and very, very expensive).
If there is sufficient interest, I may do a rake of five at a discounted rate.
The 42' will be coming out at the same time as it shares a lot of features (bogies, buffers etc.), and of course I will need one for the barrier wagon.
