To All,
Sharp eye, I agree that it does have a metal time fuse adapter with part of the paper fuse protruding.
I had written to the newpaper writer, Carlos, and asked about the type and nature of the fuse and she sent my request to Elizabeth stern presumably of the park service. Ms. Stern said only that it was a time fuse.
Regards,
John
p.s. i HAVE ASKED FOR A PHOTO SHOWING THE FUSE.
