CT's, how did Oswald's rifle end up on the 6th floor?

[Walt Cakebread]

Because there are 5 screws that attach the stock to the action.

And a dime is too thick to fit into the screw slots....  ( a worn dime might fit)

[Bill Chapman]

I get it. Did they find a dime on LHO and does it affect how he kept his prints off the rifle? Were his gloves found?

He had gloves? Do tell.
Oswald had 3 dimes on him. A dead giveaway in some quarters.

Others will disagree with 'kept his prints off'
Prints are dead easy to at least smear. The term 'unusable' comes to mind.

And a dime is too thick to fit into the screw slots....  ( a worn dime might fit)

I guess Cunningham's dimes were 'worn'.
Or the screws were.

Sorry ...

Supposedly information based on and taken from the Report.So...he filled out the coupon and let it [apparently] sit around for the 2 months you stated to earlier.
 Who does this?
Not responded to...

January 28, 1962: LHO orders a .38 caliber Smith and Wesson revolver by mail.

  So, he ordered it and it took a year and two months before Seaport Traders finally got around to shipping it to him?

Barely one inch. The blind could see that.

Maybe that's your problem. You're blind.

Here's where the rifle was found:

Wrong!....  Are you stupid and illiterate? How wide is the crack between the boxes that you have drawn the arrows to?  Two or three inches?.... How wide is the carcano with the bolt handle sticking out to the right and the scope sticking out to the left ?  (answer:  over 4 inches ) 

3 or 4 inches. It's hard to judge to exactness.

Zoom in on them both and examine the boxes and the printing and stamps on them. My placement of the rifle is correct. No doubt about it whatsoever.

Mr. BALL. I notice you have a screwdriver there. Can you assemble it without the use of a screwdriver?
Mr. CUNNINGHAM. Yes, sir.
Mr. BALL. What can you use?
Mr. CUNNINGHAM. Any object that would fit the slots on the five screws that retain the stock to the action.
Mr. BALL. Could you do it with a 10-cent piece?
Mr. CUNNINGHAM. Yes, sir.
Mr. BALL. Will you do that--about how long will it take you?
Mr. CUNNINGHAM. I know I can do it, but I have never been timed as far as using a dime. I have been timed using a screwdriver, which required a little over 2 minutes.
Mr. BALL. 2 minutes with a screwdriver.
Try it with the dime and let's see how long it takes.
Okay. Start now. Six minutes.
Mr. CUNNINGHAM. I think I can improve on that.
Mr. BALL. And the only tool you used was a 10-cent piece?
Mr. CUNNINGHAM. That is correct.

Six minutes on his first try using a dime. You call that difficult?
