Perhaps Oswald's rifle was the same rifle that Oswald ordered, paid for, was sent to his PO box, was photographed with a few weeks after receiving it, was discovered on the 6th floor of where he worked and had his palmprint!
Or perhaps not...
Corrections:
Unscientific and biased handwriting “analysis” of two block letters on a photo of a microfilm copy of a 2-inch order coupon (from microfilm that is “missing”) purports that he filled out an order for a similar but not identical rifle. But you have no evidence or documentation of any kind showing that such a package ever went through the postal service, was delivered to the PO Box in Dallas, or that any required forms were filled out, or that any such package was signed for and picked up by Oswald or anybody else.
There's nothing connecting the money order found in Virginia to any particular Klein's order.
The rifle in the backyard photos cannot be uniquely identified.
The partial palmprint was found on an index card that showed up a week later, after the FBI found no usable prints on the actual rifle.
