Just some thoughts and ideas

I saw at a gun the other day in a local gun shop, it was a 1939 42 code...8788 u, all matching numbers including the firing pin, but the receiver had that brown plum color and the rest of the gun was the normal darker bluing color.

Large Stick E/63 and the late military acceptance mark on receiver,
small Stick E/63 and late military acceptance mark on barrel

I checked the barrel alignment mark and the ser# and it all looks right ,except for the stark contrast, between the receiver and the rest of the gun.

I've seen that brown plum color on other guns and on some small parts of
guns, but never quite like this before where just the receiver was plum.

Have any of you guys seen this before and what do you think ?

I'll try and get some photos if there is any interest
