Still, need to look this gentleman up, but I got to go into the basement and open the trapdoor and take a flexible camera and look at the roof of this tunnel. There were metal strapping holding up the brick floor in the roof of the tunnel. Further in there where mysterious gears; More to come later.
Above you can see the basement entrance converted from an old tunnel. These entrances were not historical and just utilized the entrance the tunnel used instead of poking a new hole in the foundation. For years I have been looking at elaborate sump holes in basements that were all brick lined and finished, this is the first one that proved there were tunnel entrances. You seen pictures of that as well above
