Hello all,
Thank you for the additional info and comments, most welcome.
As for MACR 18889.
Page one has "18889" but page two has "11889"
But to access I had to type in 18889,
https://catalog.archives.gov/search?...orNaIds=305256
The highest macr is as Frank says 16707, so ?
Thanks to all, am looking forward to more additional info as we go forward
Alex
