Big-Bang Model 15AC

The 15AC was introduced in 1935 along with the 15FC and 10FC. Here the Antiaircraft gun graces the cover of Conestoga's catalog. The 15AC shares the same barrel and breech as the 15FC. The charger cover will be marked "No.15 CC CHARGER FOR 15FC AND 15AC KEEP CLOSED". Early 10FC chargers were marked similarly noting a 10AC, but the 10AC was never produced.


The 15AC was produced from 1935 through the mid 1960's. It was an unstable platform compared to the 15FC and was never a good seller.
