Meeting Warren Caster - by Rick Caster
From that link---------As we may recall...Oswald's name was not even mentioned by anyone in Warren Caster's WC testimony.
Oswald's name was not even mentioned by anyone in Warren Caster's WC testimony.That's true, ....but...... Lee Oswald told the interrogators that he'd see this rifle ( the carcano) and two other rifles outside Mr Truly's office at lunchtime on Wednesday November 20, 1963. So I believe that Lee was there.... He may not have been part of the group, and he could have been watching from the distance, but he definitely saw the rifles.....( and he probably heard remarks like "Boy, I'd like to get these sights on that SOB JFK" ) Caster was good friends with HL Hunt the billionaire oilman who hated JFK. and Hunt often visited Caster in the TSBD.. ) If we could know the truth I would not be surprised If I were to learn that after seeing the rifles, Lee Oswald took a note to Hosty at the FBI office in an effort to get Hosty to contact him.
PS..... If Lee recognized the Carcano as being like the one that he and De Mohrenschildt had ordered from Kleins he may have wanted to verify that the carcano was still in the blanket and that might have been his reason for the trip to Irving on Thursday afternoon.
