Lately, I purchased two RM10 revenue stamps (right bottom corner) with consecutive control numbers (192895 and 192896). However, both the control numbers have different font types. Font type I (control number 192896) seems to be more common than font type II (control number 192895). During the purchase, I also noted that control number 192890 (I did not purchase) has font type I. My speculation of the font type II is that the sheet with control number 192895 missed the printing of control number (with font type I), and that it was later printed with control number 192895 using different machine/method.
