Does anyone recognize this moster signal device and what its true value is? It was for sale at a local yard sale. Orinally it was purchased down in Rockland County NY. and maybe used on the Long Island Railroad. As can be seen in one of my pics the seller was asking $345. At this time the owner didn't want me to give his contact information online. If anyone is, send me your contact info and I will forward. See the next pic for the only markings I saw.
