Serial Number 3312361 was reported as inaccurate.

Note: Also, according to Meggers & Ehrhardt, this curved
train bridge movement is a Model 7 (EA 467C),
which they list as "Mostly Private Label Stewart".
But this info doesn't jive with their serial
number index, which lists this serial number as a
Model 9.
