What you or your Warren Gullible friends have never been able to explain, Mr Smith, is why the numbers 275 and 276 were assigned by the WC to the Paine garage curtain rods in the first place. Why those numbers? Hm? Have you got an answer?
Thought not! 
Let's help Mr Smith, shall we?
Where did the number 270 come from as the number at which to start marking the RuthPaine Exhibits?Well, I guess it's a
little more subtle than Messrs Jenner & Howlett saying 'The heck with it, we'll just start with 275 and go straight for the damn curtain rods, which are the only reason we came all the way out here to Irving'..........
And remember! First thing tomorrow morning, the two curtain rods submitted to the crime lab 8 days ago will be formally released back to Agent Howlett----------yes, the selfsame man who is at this moment in the Paine garage in Irving solemnly 'receiving' two curtain rods on the record!
