Dear Tom,
I can see the blue prices hadn't noticed them before. I would assume that the kits are etched, the only thing I've made from an etched kit is a coach and as I remember it was quite difficult and took a long time, for me anyway.
This loco was General Don on the Jersey Railway and Clevedon on the WC&P, the body is made from Plastikard and the chassis from hand drilled brass strip, wheels are Slaters a Mashima motor and flywheel.
The most difficult part is the boiler, a bit of patience is required to bend the plastikard into a circle, if you make a mess of it the first time you can always cut another piece. What doing it this way gives you is the opportunity to make a complete balls up, learn from it and start again without spending your hard earned cash.
Jim
