I never realized that the boxes that these came in were so important. When I pick up my model 28 in 3 weeks the original box comes with it. I have not seen it yet so I hope it is in as good a shape as the gun is. I remember when I purchased my model 29 in 1978 it came in a wooden presentation case. Are these valuable or something that just has collector value. Can someone give me the short course on these. Thanks
