Even though the Dallas equivalent has never been seen/found, the New Orleans Post Office Application shows that Oswald already had your feeble objections worked out and it's reasonable to conclude that if Oswald was having stuff sent to Hidell while he was in Dallas, Oswald would have had Hidell's name on that form as well.
CE2585, p. 4:

12. CLAIM: The Post Office Box in Dallas to which Oswald had the rifle mailed was kept under both his name and that of 'A. Hidell ." Page 111.
INVESTIGATION: Our investigation has revealed that Oswald
did not indicate on his application that others, including an 'A . Hidell,' would receive mail through the box in question, which was Post Office Box 2915 in Dallas. This box was obtained by Oswald on October 9, 1962, and relinquished by him on May 14, 1963.

Besides, who said that "Oswald was having stuff sent to Hidell"?
