In RIAC's upcoming auction I noticed a 1900 Swiss that has the last two digits of the SN on the back side (right side of the pistol) on the take down lever and the mag release button, is this correct and if so should they all be marked like that or just the early release pistols? My Swiss SN 2512 is not marked this way.
