Ek1 l/15

+1

to me there is a purpose of having these 2 types .
The comparison daniel shows tells us why . As the germans would say : Verwendungszweck = purpose of use . The location where it is being used .
The smaller one fits on the ring better and to me would have been added later for that purpose and used on ek1s as well .
