Blowfly (5" Gauge)

Blowfly is a 5" gauge 0-4-0 tank engine designed to be ideal for beginners, as such it is a popular first loco. Blowfly was designed in Australia by Barry Potter and has 1.5" bore cylinders and 4.5" diameter driving wheels. Originally published as a series in Australian Model Engineering magazine, The Blowfly Manual is now available containing full copies of the original articles, plus updates and upgrades to the original design.

The simplicity of Blowfly has also made it popular for modifying to other designs and wheel arrangements, several Blowflys have been built as a 0-6-0, 2-6-0, and even an 0-4-0 0-4-0 garratt.
