Need info on Empire, aka Empire of Troy, built by William H Brown in NY, 1843.

This is a side wheeler used on the Hudson River. There is a model of her in the London Science museum, built in 1904 by William H Brown (?) in 1904 in the museum's workshop. The model is currently off display. I have a few photos but would like plans (of course) or any other info to help me build a remote controlled model.
