Please help in evaluating this 40/42 Luger. I am not attempting to start the dreaded "BW" discussion, but can say the grips were on it when veteran returned (family pic). It seems that some say there were a few that did come this way, but its never yours

The mag is unmarked metal, so would likely support the idea of some field revisions. Thank you for your time.
