As to dating, one says 1880 to 1890, another says 1883, which fits, and
a third says late 19th century, which also fits.

As to make, I have been given Paillard from three people.  They came up
with this due to various construction features and the serial number.
Another said PVF/Paillard.

Robbie, Jody, and MMD are terrific!

Thanks,
