Luger S/42 1937 with PSE marked barrel

I have a barrel also with those letters but in a different sequence. Mine is a VOPO import 1918.

The VOPO import sounds interesting but there is no any VOPO marks on mine (from my point of view at least). Another point - the barrel has no any evidence of acceptance stamp or serial number.

What was a reason for VOPO to remove the barrel from a gun? It's interesting but barrel's end shows much wear with bluening peeled off.
