Do you by any chance know the specific models that are produced?
Some research notes, using known 3067 factories and MUL availability as starting point:

LCT-1V -- AoW
LCT-1E -- SW-E
LCT-5V -- Jihad (confired about to enter MoC production in TRO:PP)
Stinger (MMM, Canopus IV)
Stinger (DCM, Detroit) -- STG-6L (ref TRO:PP)
STG-3R -- AoW
STG-3G -- SL
STG-6L -- CW
STG-3P -- Jihad (refit only, ref TRO:3085)
