Here are some; the first one is free and the other 2 cost a little. Just remember to reduce 1/32 by 24% to get 1/43.

Do a search for printable cardstock buildings, you'd be amazed at what's out there.

most buildings are 1/32nd, you can use them too, but have to scale them to 75% while printing.

is that the one you were looking for?
