G'day.
I was poking around on the Model Engineer website and under the 'Features/Magazine Reprints' part of the header bar I found some interesting articles such as this one
http://www.model-engineer.co.uk/news/article/me-centennial-collection-issue-7--parts-1-and-2/5702.
This issue is all about steam engines, including a 1906 oscillator that will fit inside a .22 rimfire case.
All the old magazines in this section are well worth a read.
(I'm getting close to building my first steam engine........I blame you lot
)
