The larger horn with the stamped "rope" design in the butt plug, and turned spout on the small end, is a Lancaster horn, probably from the percussion era in the mid-1830s to 1840s. The brass tacks are later decoration put on the horn by an owner.
The smaller horn with faceted spout tip appears earlier. The photos are a little too fuzzy to see if there is any type of hole in butt plug that would indicate a strap attachment at one time. Assuming there is no hole, and it was a bag horn, it might be from the earlier flintlock period... but this type simple horn was made over a lot of years back east, flint and percussion eras, so you will probably never know when it was actually made.
