In the early days, the Lodge Standard Flap was changed every one to two years until 1968. Some of these Flaps, look the same as its predecessors, but had minor changes in them. There has been 21 flaps with 20 variations, for a total of 41 flaps, which have been designated as the Official Lodge Standard Flaps.
Currently we only change the Lodge Standard in a Noac year if the LEC approves the change. Listed below are those Flaps and the Years they were used.
