Your gun was sold by H&D Folsom of 312-314 Broadway,New York,N.Y.It sold in $13.50 circa 1880.
As stated by others your gun is yet another example a gun bearing a spurious English makers name,made in Belgium, sold by Folsom. Folsom sold guns with over 100 different house brand names. Many of which suggested English origin.Perhaps the most badly abused name was; W.Richards! There is currently such a W.Richards; Folsom gun offered for sale on a well known auction site; the write up states the gun was made by Westley Richards! Buyers beware, research such guns with great care before purchase.
