Mr. BELIN. Can you just give us one or more of the magazines in which this coupon might have been taken?
Mr. WALDMAN. Well, this coupon was specifically taken from American Rifleman Magazine, issue of February 1963. It's identified by the department number which is shown as--now, if I can read this--shown as Department 358 on the coupon.

So, not only did the department number identify the magazine but also the month of the issue in which the (in this case) 36" MC rifle was advertised.
I don't think you can any more specific about which item was ordered by using the item number in combination with the department number!
And that's not all. It also explains how Klein's, in later issues of the magazine, continued with C20-T750 for the 40" rifle, as the department number on the coupon would confirm that a 40" rifle was ordered.
Thanks for clearing that up, John
