I've taken the fist step in identifying my M1, contacting the cmp and requesting the cmp cert letter. I've looked up my receiver serial number and barrel number. which by the way is far from being shot out. Both match 8/44. I've ordered from ebay the scott duff book to match the rest of the drawing numbers. what I need help with is this "rack number". Are there any vets out there who can help me with this. All of my research points out that this may have been in an armory stateside or overseas and may have never seen real action. It could have been assigned to a motor pool, kitchen etc, or even a boot camp range rifle. Any help would be great.
