Bill; Sadly the further west the compilers of the OR got, the less material they included. My estimate is that less than 10 percent of the TM records were included in the OR, and that the basis for inclusion made neither rhyme nor reason. Very little of the non-included material has been microfilmed, and it will probably take a trip to Washington to find what you are looking for.

As a note when you are going through records at the Archives, if it has a blue "copied" stamp, it is in the OR. If it doesn't it isn't.
