I can just make out it says Otoneg 2.
Thanks Trond and friend.
From the LargeFormatPhotograhy forum.....
"I think that you need an OTONEG, OTONEG-2, or maybe a TAUNEG negative carrier. These are also compatible with the Laborator 1000. Like Leitz, Durst uses code names for many of their parts, and from what I understand they go as follows:
OTO => Laborator 54
TAU => Laborator 1000
FEMO => Laborator 1200
LATI => Laborator 138/S-45
LA => Laborator 184
So, an "OTOCON" is a condensor for a Laborator 54, a "TAUNEG" is a negative carrier for an L1000, and a "LATICO" is a condensor for an L-138."
