Could you tell us, Colonel, of what it is a photostatic copy?
Colonel Folsom. It is a Photostatic copy of the U.S. Marine Corps Scorebook for use with the U.S. Rifle, Caliber 30 M-1.
Now, this scorebook is issued to each individual at each time they are sent on the rifle range for qualification or requalification.
They are maintained by the individual and are used to provide the individual with a record of the idiosyncracies of the weapon, and the weather on the day that the entries are made. This is referred to in the Marine Corps as the zero of the rifle, because the sight settings are individual characteristics of the particular rifle used. That is, he may—this rifle may require a half a point more windage under the same wind velocity than another rifle, and that the scale by yards may require adjustment depending upon the range that is being fired.
Mr. Ely. This book, then, is used by the individual Marine prior to his firing for record in order that he can zero his weapon so that he will do well on his record firing?
Colonel Folsom. This is the purpose. And it should be maintained even on the day that he fires for record.
In this particular record, it would appear that the entries were rather limited. As a matter of fact, it was not adequately maintained for the purpose for which it was designed.
Mr. Ely. Is it possible, Colonel, to tell anything from this scorebook, assuming for the moment that it was accurately maintained, concerning the marksmanship of Lee Harvey Oswald?
Colonel Folsom. Well, yes. But very generally. For instance, at 200 yards slow fire—on Tuesday, at 200 yards slow fire, offhand position——
Mr. Ely. You are referring, are you not, to the page designated 22 in Oswald's scorebook?
