striations on win lever action receivers
were win lever actions released from the factory with what looks like scratches on the action sides? i have several older levers actions that have lines that look like they are under the blue-finish. thanks eastbank.

They are forging lines in the metal. They usually run horizontally on the sides of the receiver and will curve some. When the receiver was forged the metal is folded and scale and impurities get trapped in the folds. When the gun is new you would not of seen them but over time the metal in the fold oxidizes quicker than the rest causing loss of blue over the forging lines.

I've seen/owned quite a few.. Not just levers.. Over the years I've read, and been told, they were milling marks.. And yes, they appear "under" the blue.. I have an absolutely like new Model 12 Trench gun with these marks under the FACTORY parkerizing.. 0 -
They are forging striations, not milling marks. As Bob pointed out, when the steel was cold forged, it was folded over on itself (multiple times). Nearly all Winchester models will exhibit the loss of bluing along the striation lines. 0 -
Schooled about this on gunboards,realized I had an example.1996 restoration by myself/Turnbull restoration.Forge lines appear as dark streaks under carbonia blue.

The reason the forging lines showed up right away in your gun is over time moisture works its way deeper into folds causing the metal to oxidize. When you sanded it down it looked great with the naked eye but if you put it under a microscope it would of looked porous.
