In reconnoitring the 'Nottingham & Leicestershire Steam & Country Show' at Stanford Hall near Loughborough, way back in July on the 3rd. 2008, I was able to see a steam wagon, two traction engines, and a plethora of working scale steam engines. The gears, pistons, regulators, and steam whistles are all different in some way, whether its the scaled replicas, or the restored steam engines, it seems that every Victorian town had a workshop that made them their own way!
The other aspect of a show like this one, is that you can become a hunter (not a scavenger) of SteamPunk paraphernalia, a lot of stalls have what other people call junk, but we know better “what !”; cogs, gears, gagdes, brass doorknobs, and the like, and even Victorian lamps can be found. I myself bought a solid brass shoe-horn, very helpful when your servant is not to hand!
On the whole well worth the reconnoitre.
