Judging by the size and style of the numbers on K&C Tunisian Tiger 125 I suspect it was modeled on those of s.H.Pz.Abt.501. During the North African campaign the Tiger units were still a mix of Tigers and Pz.IIIs
In October 1942 the Tigers of s.H.Pz.Abt.501 were
Command Section
01,02
1st Company
100,111,112
121,122,131
132,141,142
2nd Company
200,211,212
221,222,231
232,241,242
In February of 1943 this units tanks were attached to Panzer Regiment 7 as 7th and 8th companies so the numbering was changed accordingly:
7th Company
711,712,714
721,722,724
731,732
8th Company
811,812,813
821,822,823
831,832
