Which tools are best for working on Air guns?

[45flint]

As a vintage collector the “tool” I use the most when I acquire a new airgun is the stainless steel pad below made for removing rust. When used with thin oil it is amazing at removing rust imperfections often to the point they are not noticeable. It doesn’t affect existing bluing. With some guns where the rust has not progressed too far, it can work miracles. After unboxing its the first thing I pick up cause rarely does blued metal come perfect.
