OO/HO watt and boulton reciprocating atmospheric steam beam canal pump C1750's

ok so on my model layout is a canel that has a pump house for topping it up.. and as all pump houses have large windows and thus able to see inside i thought i would see if i could build a Watt and Bolton reciprocating atmospheric steam pump C1750's ... so out with cad and on with the printer... :) oh i did i say why not make it move with a motor under board... next the building so more windows and doors...
