Need info. on a bell from a ship that is now an historic

[ms7]

landmark. The Captain Meriwether Lewis.

I have a ship bell that I acquired years ago. It's a brass bell about 16 inches in height and it has the engraving of "Captain Meriwether Lewis 1932" on it. Doing some on-line research I believe it is from the old Dredge named the Captain Meriwehter Lewis which is now a historical landmark and museum in Brownsville, Nebraska. (see the below link for more detail)

If someone could provide me with a way to get this appraised I would greatly appreciate it. I hope to get some pictures of the bell up soon. Thank you.
