In regards to serial numbers,
I'm a retired gunsmith and I've recovered obliterated serial numbers using the magnetic particle technique. Basically this process only works with ferrous metals, and the serial number had to have been stamped, not etched or rotary engraved.
It involves electrifying the numbered part (frame/receiver) in a specific way that would cause a finely ground iron powder floated on fluid over the spot where the number was stamped to gather over the denser metal caused by the stamping process in the image of the letters and numbers. Snap a series of photos, and there you go.
It's a common and relatively fast and easy process, and the equipment to do it isn't terribly expensive.
