Glad you have it working- they are a decent mower . I would agree its probably 1954 - 1958. Under the magneto cover there is a date mark XX XX month and year but the engine and magneto may not be the original one. This is the standard Atco 14 and had a simple steel catcher .Google for images . The deluxe 14 has an alloy 2 section landroll, longer fuel tank. micro adjusters for the bottom blade, usually an all steel cone clutch, low tone large muffler and a much larger alloy catcher which hooks over the front engine mounting bar.
