The US was "a durable deflationary economy" for pretty much the whole 19th century, and first decade of 20th century. Things started to change once FED was created and given power over money supply.
Not sure what you're refering to, the 1873 panic wasn't exactly the finest hour for US economy. I guess that's not what you want to get back to.
As for the rest of the 19th century, the data we have is mostly consumer price indexes, but I can't recollect another durable deflationary period in the century.
