PRIMER (Percussions Caps) Box from Kynoch

This is a tin box with a raised base, showing the Kynoch Lion and the adress of Kynoch around it. On the upperside a paper label as shown.
As it was empty, I liked to know, how this Percussion caps looked…
4, 5 or 6 pedals?? and the size of them…
Maybe someone can help.

I have the same tin / label but it only has one copper cap in it, it measures:
9.05mm at the 4 petals, it is 6.23mm tall, 6.21mm in dia. at the top and the inside dia. is 5.76mm
hope this is of help
