Hi, my name is*****'m a certified appraiser and I'd be happy to help.
In the 19th century, most furniture was made by individuals, or by very small companies. It's virtually impossible to determine a maker without a mark, as there were thousands and most are lost to history.
This is a late 18th century Victorian Eastlake example. With the advent of the railroad around 1850, it's unlikely that this came in a covered wagon, as it was made closer to 1880-1890. Oddly, these are very often called "covered wagon rockers," even though these were made later than that--earlier examples were brought in covered wagons, and the name stuck.
The resale value on these in very good condition, at auction, tends to stay below $100, unfortunately.
I see you have not yet rated/accepted my answer. How can I help you further?
