Where do you get this stuff???
Some hints and tips:
-Steamshows and gas engine shows!!!
Most Steam and Gas engine shows in rural areas feature large flea markets. These are not the "Mom's crap from the 1970's" fleamarkets. This is where you will find everything from vintage display cases for your gadgets, to antique furniture, to guages, to that vintage tool or widget that will add an extra detail and authenticity to your kitchen or workshop. Plus, the deals are great at these shows. (and the people are really nice too:)
Some deals I have found at these shows: general store counter display case 10.00, antique pulleys for shaft driven equipment 5.00 apiece, 1850's drill press with giant flywheels 75.00 etc. etc.
-Want to play with some real steam? Pick up an antique toy steam engine off of ebay. Worn and battered ones go for cheap, still work, and look great on a shelf. I have one that is electric and safe to run in the house, another that requires alchohol tablets and melted a hole in my driveway.
-Many big cities have architectural salvage places. Chicago has Salvage One, Baltiumore has Second Chance and Housewerks. These places have all sorts of Victorian details that can spruce up everything from a house to a studio apartment. Last great deal, Secondchance in Baltmore had sections of Baltimore and Ohio RR victorian Iron fence, 20 feet for 500.00
