Christopher,
Perhaps No Longer Interim Director Hammarberg can email you a copy of the paper
his LZA predecessor, Donald Friedman, presented in Philadelphia at the
Preserving the Recent Past 2 a few years ago "Multiple Structural Causes in
Glazed Brick Facade Failure".
Or since you appreciate pickled peaches, I'll be glad to fax you a copy if you
let me have a fax number. Only 6 pages.
