In the late 1960's I bought a Civil War Collection up in Ohio and there were several of the red colored paper fuses in the collection, none of them had the seconds marked on them, I don't know were they came from, they were not in a box, but also in the collection there was a box of Franklin fuses, I still have one of the red ones, and 2 of the Franklins, one marked 6 sec. and the other plain. The collector I got the from made several visits to Bannerman Island in N. Y. and may have picked them up there, as he did several other small items he just picked up, of course Bannerman bought most of the Civil War surplus of the U.S. Government, and at that time of my friends visit I don't think there was anyone around that could have answered that question, and he is dead now, also. That still doesn't help.
