Tools would most likely include, the black knurled SAT (screw driver), an aluminum rod, a brass core brush tip and a brass core swab. They would have most likely come rolled together in some brown tissue paper...
Here is a photo of the tools for a 357 of that vintage.
The tools would have most likely been the same for your pre 18, except in .22 cal vs .357 cal... The tissue paper was a brownish tan like the paper in the photo under the gun and the Vapor paper.
