Rose Mary - I am confused. You say the NPRC (National Personnel Records Center, ST Louis) sent the records in 1982. The fire ocurred in 1973. Possibly they were recovered but still the date of tranferal seems odd. What is the name of the office they sent the records to in Pittsfield, Mass?
Are the records medical records?
Did they give a reason why they could not allow you to have the records?
Now when I have said all that I still probably can not help you but when you answer maybe some of thes other very knowledgeable people can. I hope so.
Have you gone to the NARA site? NPRC is a branch of NARA ( National Archives - based in Washinton DC but with branches at other places)? If not go there and see if you can find a hint. Just type in NARA and you should be on the site. Mary
