I certainly did not mistype when I suggested that most double guns made without fore-end wood were made well after the Civil War and I would date this gun well after the date otherwise suggested. Below is some of the information I have on the PA Shuler family. I have seen what I believe are pre-Revolutionary war double barrel rifles [obviously made in flint] and many others == all with fore-end wood--, but those that had only buttstocks and no fore-end wood only are generally quite late.
Shuler, Caleb William (1825- ). gunsmith. Perry County. Caleb William was born June 26, 1825, a son of Samuel Shuler, Sr. He was a gunsmith and married Isabella Charles in 1844. He lived and died in Liverpool.
Shuler, John. gunsmith. John Shuler was born near Quakertown, Montgomery County, and later moved to Millerstown, Perry County. He died prior to 1827. In 1799 he married a Miss Thomas of Montgomery County who predeceased him. Their children included: Samuel, Sr.; Lydia, born in 1801; Polly, born in 1803; Leonard, a gunsmith in Lewistown; John, Jr., a gunsmith; and Joseph, later sheriff of Perry County.

Shuler, Leonard. gunsmith. 1829-31, 497 High St., Philadelphia [Philadelphia Dirs.; Stranger's Guide]. Before 1832 Shuler was a gunsmith in Lewistown, Mifflin County. On 26 July 1832, George V. Stewart placed an advertisement in the Juniata Gazette saying that he had bought out Shuler's gunshop. Leonard was a son of John Shuler of Perry County and was probably born in Millerstown. He married a native of Lewistown and both died there.
Shuler, Samuel (1779-). gunsmith. Liverpool, Perry County.
Samuel Shuler . . . was born in Quakertown, Pa., December 23, 179 [or 1799?]. He learned the trade of a gunsmith with his father and worked at that trade during the earlier part of his life. Having removed to Millerstown, he married a Miss Jones, a native of Raccoon Valley; and they resided in Millerstown until 1827; in the spring of that year he removed to Liverpool, where he followed the occupation of a gunsmith until 1834. At this date he embarked in the grocery business, in which he continued until his death in August 1875. . . . His marriage to Miss Jones occurred September 16, 1823, and she died November 10, 1872. Their children are: Caleb William, born June 26, 1825, a gunsmith, married Isabella Charles in 1844, lived and died in Liverpool; Elizabeth; John Ramsey, born March 2, 1829, married Mary Rook, July 28, 1852, and resided first at Liverpool, later at Bloomfield, where both died . . . .
