Finndog,
The book Arms Makers of Lancaster County, Pennsylvania by Wood and Whisker, lists a Henry Deeds (1811-1888) as a rifle barrel maker and gunsmith. About 1838 Cornelius Reichwein opened a gunshop, in which Deeds worked for many years. In the 1850 Census of Industry, Deeds employed 2 hands and made 3000 gun barrels valued at $4875. In the 1860 census he made 1100 rifle barrels valued at $1375. There are some additional details in the book but 1860 is the last date mentioned.
A. Merwyn Carey's American Firearms Makers lists "Deeds, H.W., about 1775. Shop located at Reading, PA, made flintlock rifles." That is all Carey wrote.
It could be that H.W. was Henry's father. Or could be Carey's date is incorrect and they are the same man.
