1859 map of Florence

Griffin Pipe is correct, although it is a little further down. There are a couple of other businesses in there as well. I may be mistaken, but I don't believe that what is Griffin Pipe today was part of the original works. I am not sure if any buildings from the original works are even standing anymore.
 
i have been in Griffin pipe several times to work (being punshed) the place is sort of a dump, the building i was working in had an partly open wall (missing bricks) and trees growing inside, maintance dept, LOL
some of the building were very old at least as i can tell turn of the century or maybe older
