A lot of my modelling over the last few years seem to be so I could have a break from that damn Wa kitset, which I've already posted here. Even though it's not finished. I wanted to make a locomotive, but also make something that would actually work, that I could learn from, and therefore be rewarding.
Even from my minimal experience, the Backwoods Miniatures kits from the UK were top-shelf. I bought their Sn3 0-4-4-0 Mallet, 009 Beyer Garratt that I've since sold (and regretted doing so), and a Sn3 0-4-0 vertical boilered "Bitsa". The big plan was to convert them all to Sn2, which was why I sold the Garratt. It just looked too difficult at the time, to convert.
The 0-4-0 seemed the easiest kit to start with, and hopefully I'd have a better result than the Wa kit which was going through one of its, "I want to inexplicably run like a ruptured tortoise" phases.
It's a real pity that Backwoods Miniatures kits are no longer made. Even the little 0-4-0 is a work of art, in my opinion. The simple photo-etched fret and castings fitted together perfectly and make up into a lovely model. I had a few challenges, but the excellent engineering in the kit meant that all problems were my own creation.
