The original Korber Models Company (owned by the late Ernie Korber) located in Perth Amboy, NJ made accurate O gauge models of CNJ ( and NY&LB) brick interlocking towers. This type of tower had ep/Electro Pneumatic switch machines inside...so your model interior is correct.
The wooden construction towers on the CNJ/NY&LB such as Red Bank, Matawan, Sea Girt all used Armstrong levers.
Going to college in the late 1960's, I worked as a CNJ Towerman, qualified on all CNJ towers from PS/Phillips Street in Jersey City, NJ to PU/Phillipsburg in Phillipsburg, NJ and Branches.
