Oh my YES.
I reconstructed 10+ shapes of glass viewing windows from Freedman's Cemetery
in Dallas TX  (1869-1907).   It was a pet project of mine and I didn't
cut myself too often.   We recovered hundreds of viewing windows,
only one of which came from a cast iron coffin.   I have a lengthy list of viewi
ng
window references at home, I will post it tomorrow.
