Hi Fernando,
I guess the
Bitte was meant for me ...
It is really hard to discern but these do not seem very early to me: their conical shape with the broad and flat rear section would make them ideal for firing in an upright position.
Furthermore, the surface of the one on the right looks so smooth that it should be checked if it is possibly found iron.
While almost all these barrels kept their traditional Gothic form (octagonal or sometimes hexagonal) for hundreds of years I should attribute these two tentatively to the 18h or 19th century and call them noisemakers.
Again, it is very difficult to tell and I have to resort to a sort of feeling which should by no means impair your having fun with them, though!
Michael
