Strange primers (?)


#1

these items look like primers.
Something strange (if they are primers) is the fact the open side (where the powder is going out when firing) is bigger in diameter (7.25 mm) than the oposite side (where the hammer sticks) (7.15 mm)

length : 6.80 mm

Any idea ??

This is for sure a primer for either percussion or time artillery fuze. There are so many varieties that it is impossible to say with precision for which fuzeā€¦ and which country.
