I have the case files for my ancestors, not an application. I can tell you that I ordered them from the National Archives - Southwest Region in Fort Worth, Texas. You can even telephone them at (817) 334-5525. However, since I knew the MCR # or Enrollment #, I sent an email to archives@ftworth.nara.gov, provided them with my ancestor's name, the tribe, and enrollment # and asked them to telephone me so that I could provide them with my credit card # to pay for the records. The records are $10 for 1-20 pages and an additional charge for each page over 20 pages. They telephoned me no later than the next business day, I provided them with my credit card info, and I had the records within a week. Thus far, I have purchased 9 files. Good luck! Lori
