i found a new use for brass paper fasteners....they are a quick and dirty substitute for rivets. I have a k-line warbonnet that had the coupler broken off. There wasn't enough left under there to replace with the correct coupler. I did have a hole. So, to easily attach coupler, I used a brass fastener. Didn't even have to take it apart. Today, I noticed my crane car had a busted up wheel set. So, I junked a crappy caboose and took the wheel set off. Once again it did the job. Saved me a trip to the store, it was cheap, and requires absolutely no skill!!
