I am looking for an unknown machine to complete my mad scientist set. I of course have all the other pieces to trade with if you are looking to complete this set. I only need to catalog but I could also buy. I also have the complete sets of blue, regal, modern, astro, cabin, sleek, rococo, robo, campus, alpine, spooky, jingle, harvest, polka dot, and scifi. So if there is an item you need to catalog let me know. If you just want bells name your price.
