Wondering about the value of Winchester trench guns. one is a parkerized made in 1942. possibly U. S. Navy firearm due the markings on the stock. Is 100percemt correct. The other is also 1942 dated. It is blue also 100 percent correct. Has two small scratches on the left side reciever. I am 75percent computer illiterate and do not know how to post pictures. The parkerized firearm I would rate at about 85%and the other blue 97 is about 95%. Any comments will be greatly appreciated. I need to establish realistic value to these items due to the fact I may be selling these and other items.
