Two new Swiss - Questions

Both do not have the last 2-3 digits of the serial # on the takedown lever (at any location).

As far as I know this part was originally numbered. However, as it is one of the weak parts, it was not unusual to have it had replaced.

The 06 Cross in Sunbust has the correct disc mag and the 06/24 has a mag numbered to the pistol.

As far as I know, only the first series (P1900 #1-1000?) had ordinance numbered mags. However, again, it is not unusual to find mags with the last two digits of the s/n on the bottom of the 06/24 mags (only wood). Why this mag numbering was only added to 06/24, I don't know.
