Military report of seperation -Help understanding report

Hi, I just picked up a copy of my grandfather`s Report of Seperation  from the county courthouse. I have a question as to what he would have been entitled to. The following is what it states which is the obvious, my question will follow at the end.
Rank - T/Sgt
His MOS - Airplane Mechanic-Gunner 748
Dec and Cia - ETO, Distinguished unit badge GO # 50 Hq AF 17 Jul 44,  Air metal GO #88 AF 7 july 44 W/20LC
Purple Heart GO #49 Hq AF 11 Aug 44
Service schools attended - Gunnery 5 Weeks
Military Qualifications - None
Total length of service - Continental service-1 yr 9 months  22 days  Foreign -1 yr 5 months 23 days
Remarks -  15 days lost under AW 107
                  3 overseas bars
                   1 Lapel button issued
                  ASR score 92 points ( 2 sep 45 )
My question is :  Would he be entitled to a victory medal (ribbon), American capaign ribbon ?
He does have  a good conduct ribbon with his eto ribbon w/ 3 battle stars,DUCw/olc, purple heart and air medal.w/2 olc( I have these) I also know that on his uniform he had a armament specialist patch on his sleeve and a Engineering specialist patch among his belongings.He was a Ball Turrret gunner Is it possible he was a ap armour while in the ETO and then when he came back to the states he earned the engineering specialist? I know he was all over the states at different bases both before going overseas and after .  I am kind of at a loss with understanding this and it seems based on what I know ,some things are missing on this report.  By the way, he was discharged from Traux field Madison WI on Oct 18, 1945. Any help with this would be REALLY appreciated. Thank You!
 

Thanks for your reply. Any reason as to why they would not be listed on his seperation paper? They didn`t list that he had 3 battle stars on his ETO ribbon, his good conduct medal or that he had a OLC on his DUC ?  They didn`t even list his schools he went to or qualifications or that he was authorized to wear Aerial Gunner wings.
Could there be other information listed on other paperwork like a DD2-14 , etc? All his paperwork in St. Louis ,MO I was told was destroyed in the fire.Ther just seems like a lot of information is missing on this seperation paper. An opinions?
