I don't know anything about this aspect of the case so I read the first few pages of this thread but my head started hurting.
Surely, at the very least, the image above is proof that tampering with the evidence, or the processing of evidence has taken place. As i read it all the writing is Day except the Howlett signature(s).
Yes
The top copy is the one with Blue and red ink, the bottom copy (the WC exhibit) has been altered by Day
Not sure this was alteration as such, Mr O'Meara.
This is what a BW copy of the form must have looked like after the rods had been submitted & tested, but before they had been released-------------

Lt. Day added a 3/24/64 signout to the original and a 3/26/64 signout
to the copyand there is no Howlett signature to say he has received the rods back. If Day is willing to change the date of the release why should we trust the date of the submission?
The rods are collected from Mrs Paine's house on the 23rd and taken to Day, maybe the morning of the 24th. He writes in a fake submission date and releases them on the 26th.
I don't think the submission date is fake. What's fake is the elaborate 'finding' of two curtain rods in the Paine garage 3/23 and the contrived marking of them as Exhibits 275 & 276. The WC on-the-record visit to the Paine garage only took place BECAUSE two curtain rods had shown up elsewhere---------two curtain rods that, because of where they were found,
needed to be tested for Mr Oswald's prints
