Here are Dunechaser's(Andrew's) three Steampunk MOCs.
The H.M.A.S. Fearless is a steam-powered airship in Her Majesties Royal Flying Corp.
Leftenant Cavendish's Marvelous Amphibious Contraption is on a voyage of discovery in deepest uncharted Asia, Leftenent Henry Cavendish of Her Majesty's 13th Expeditionary Forces improvises a means of vehicular transport, using a native canoe, wagon wheels, and a boiler of his own invention. His musket also spews Greek Fire.
Mr. Renoir's Ornithopter is unknown to most modern historians. Pierre-Auguste Renoir followed in the footsteps of great artist-inventors of the past (including his hero Leonardo Da Vinci), fabricating fantastic winged contraptions and flying them throughout the French countryside.
There they are. Enjoy!
