Thanks for the replies and info. A little googling of the Bodenheimer's came up with this info extracted from genealogy.com:
... Mr. Bodenheimer was a wheelwright (History of Fairfield County, Ohio p239 and Centennial History of Lancaster p72); Came to Lancaster in 1817 as a wheelwright - Changed to gunsmithing in 1837 - Introduced the first long range rifle and globe sights seen in Lancaster -died sometime in the fifties (Centennial History of Lancaster p340 -341); Was engaged in making spinning wheels at an early day (History of Fairfield and Perry Counties p192)....The 1859 Circleville and Lancaster (Ohio) Directory lists William and his son William as living on Mulberry between Columbus and Canal and the Northeast Corner of Columbus and Wheeling...
Other internet research says there was also a second son John that was a gunsmith.
I also see there was what looks like an earlier Bodenheimer rifle posted on these pages back in November:
http://americanlongrifles.org/forum/index.php?topic=37925.0 Found this about the lockmaker on justanswer.com: Robert Biddle and William Canby Biddle were brothers who founded "R. & W. C. Biddle" in Philadelphia around 1837. The company later became the Biddle Hardware Company. They were, at least for a time, located on Market street in Philadelphia. R. & W. C. Biddle were importers and dealers in foreign and domestic hardware, cutlery, guns, and "heavy goods." The company made gun locks from 1847 to 1861.
Any sense from you fellows if this might have been made in the time period of Sr. or one of the Jr.s? Stylistically to me it falls right in the 1840-1860 time period confirmed by the lock so it could go either way.
