A second version of the system, called "speedline", was produced starting from 1937, in which the realization was simplified by eliminating the locking system. This involved a longer bottom, but was advertised for the possibility of filling with one hand (in fact, to unscrew the bottom you still use two). Since 1942 about the system was further revised (with the version called "wartime" by collectors) using a button in celluloid instead of aluminum.
