If I'm correct, then where on that document is it stated that the money order should have had on it the endorsement stamps of each of the three aforementioned entities?
That is correct.
There is path a money order travel, Oswald would have to purchase the money order send it to Klein's. So Kleins would be the 1st endorsement and that would be to First National Bank of Chicago next 3 would be the path in which this money order would go to its final destination.
Once Klein's had placed their endorsement stamp on the money order, any additional endorsement stamps placed on it would have made it invalid.
On the back of the money order we read:
"More than one endorsement is prohibited by law. Bank stamps are not regarded as endorsements."The money order would need to get back to Kansas City which is the same place 5 other money orders that Oswald used for other things. After the assassination, a postal inspector from Dallas suddenly says he found a stub for the money order then when he is later interviewed by the WC, amazingly he can not produce the stub which he had brought to the investigation initially telling the FBI first. The inspector who initiated the conversation about the alleged stub from the money order had the last name, Holmes. Again when interviewed he could not produce this stub that he had offered to them initially but more importantly he never commented on the postal regulations for the weapons. I have a tough time trying to explain how Oswald could have 5 other money orders in the K.C. postal center where they all of them would normally end up but the one you show was already in D.C. when there is no reason for it to have been in D.C it should have been maintained or simply located in K.C..
I don't recall Harry Holmes saying that he had found the stub. The postal regulations for the weapons were met. The regulations for rifles were quite lax. Stricter regulations applied for concealable weapons like the revolver. However, they didn't apply to Oswald's revolver since it wasn't shipped by the Postal service.
At that time, there were two places where cashed money orders were sent. One was Kansas City , Missouri. The other was Washington, D.C. From the following document:

...when the Postal Money Order in question would have been received, approximately three fourths of the money orders were being sent to Washington, D.C. and the balance to Kansas City, Missouri."The Klein's money order was sent to Washington, D.C. At the US Dept. of Treasury, the money order received it's File Locator Number.

How could he send the envelope, money order and the same money endorsed and dated the same date? Did they have FedEx overnight delivery? When did he take possession of the gun
The date of March 12 stamped on the money order and on the envelop was the date that the money order was purchased and the date that it was mailed. The envelop, with the money order in it, was mailed by airmail and was received by Klein's the next day. The money order passed through Klein's cash register that day and Klein's shipped the rifle off a week later. I'm not sure when Oswald received it.
