Dec 1944 thru Jan 1945 Just about everyone has been thru a overhaul or in battle they were cleaned in mass pots and put back together. Parts were always mixed up but there is always a slight chance of a nice original or one that almost every part is still intact. Most have been put back together. Cosomoline is added to these rifles at any point and is most probably just a heavy weight grease on it. What was the asking price? Rick B
