I have ordered a couple of Military Service Records but not many Pension Records. I was given Pension Records of my Wife's ancestor which had some detailed information about the property they owned, etc.
Don't believe everything they tell you about the burned records---not even the NARA archivists. I've heard many examples of people who were persistent and eventually got a file sent to them. Also, a WW2 Vet's military records can be found in the unit's records at the NARA Library at College Park, MD. Besides duplicate copies of the General Orders that issued certificates, medals and duty assignments, there are Morning Reports, artillery Daily Journals, and other documents that may detail events in a soldier's career.
I had requested records from NPRC, St Louis 10 years ago and was told that they had been burned in the 73' fire. On the reverse of the request form there was a phone that you could call for further assistance. I contacted them and they put me in contact with a volunteer researcher who did a 'hand search' of a unit that my father was in.(he was in several outfits in his 20 year career) Several weeks later I received several documents of my fathers 20 years in service...well worth not taking 'no' as an answer.
The fire destroyed 80 percent of the records held for Veterans who were discharged from the Army between November 1, 1912 and January 1, 1960
