Serial Number 11054949 was reported as inaccurate.

Note: The Plate type '3/4' doesn't appear match my
Riverside movement
My Riverside movement no. 11054949 (c1901) is
'Bridge' type (per your Plate type reference
page).
I see other images in the database with similar
'Bridge' plates, e.g. 12560736, 13034981,
16198917, 17031809.
Images in the database with '3/4' plates have a
different serial number range, e.g. 10088259
(c1900) , 7423977, 7364234, 7158397, 7076734.

There appears to be a design change sometime
between 1900 and 1901.

Regards,
Steve
