Fettbusche black with additional unknown producing mark

[samland]

Hello !

Here is bakelit black fatbox.

"S" - phenolharz (bakelit) mit zellstoff als fullstoff.

"22" - Bebrit - presstoffwerke GmbH, Bebra und Geschlothauer, Ruhla.

But what mean a code : bottom - 2468 4, top - 2469 4 ?

I`m first time see such an additional mark.

The 2468 and 2469 numbers refer to the two component parts of the fettbusche.

This is understandable, but what do these numbers mean.

This is the first time I've seen it on these banks
