Look at pic #2, the back of the clip blade.
It appears that there was some pitting, or possible numbers that were buffed out. It appears to be rough under the polishing.
The polishing doesn't not appear correct to me either. If it was mirror polished, then you could see clearly reflections of things in the bolsters or blades. Instead it looks sort of hazy & I do see the waviness in the bolster.
IIRC, if these were polished, it was usually only on the mark side of the blade & the pile side had a brush finish like you get from Scotch Brite belts/wheels. I don't ever recall seeing any of these that were so highly polished through out the whole knife. Then as I said, the polish doesn't look right. It is too hazy for a high polished piece of steel or nickel silver. It almost has the finish I get when I am sanding bolsters with micron paper up to 8000 grit, shiny, but not the mirror finish one achieves with buffing wheels & fine compound.
Just my opinion, but it looks like it has been thoroughly reworked to me. I am not an expert on the Schrade bone jigging patterns, but it doesn't look quite right to me. The pics are too dark to show the jigging very well.
