Serial Number 835530 was reported as inaccurate.

Note: will i am not sure, it is a 3 finger bridge not a
3/4 plate. the other thing is that i can't find
any books that show a grade 375. other than that
the discription fits
Curator Response: Thanks for the report. A 3-Finger train bridge is still considered a 3/4 plate movement.
