First thoughts - this is an impressive size. 15 1/2cm long and jus under 11cm tall, the complete model certainly has presence. I suppose in G scale (1:22.5), it really should, and I really ought not to be surprised.
Part fit was excellent. Apart from opening out some holes for the steering (which does work), it's a case of sticking part A to part B. The paint seems to stand up to glue pretty well, and while the weathering isn't sophisticated, it works pretty well. Mud and panel wash would enhance it, but I plan to load this on a railway wagon at some point, and assume it will have had a little bit of a wash before shipping.
Posed on the prototype, all I learn is that tractors are a can of worms as far as details go. The real thing has a different exhaust, but another in the collection uses the same stack. I'm thinking that on-farm modification was common, and if prototype fidelity is your dream, pick one, and model it.
Did I enjoy the build? Yes. I wasn't in the mood for heavy modelling, I just wanted to stick bits together. At least a large box has been removed from the office. Or at least it will one I've squirelled away some useful parts, including a rather nice tractor seat. But that is for the future...
