That blower fuse design started in 1986 & MB rejected using ATC type fuses due the the many failures of fuses & fuse boxes (BMW & VW) that used that design.
MB first used ATC style fuse on the W140 chassis(late 1991) & all replacement chassis types.

Rarely does MB make that type of change during a production run.
