Finding reference files for stock HL2 models / GM playermodels?

[LambadaCorez]

* pretty new to rigging / bodygroups so bear with me *
For some reason, when I decompile the models contained in either GM or HL2 (using crowbar), they never come out with a reference file.
For example, lets say that I decompile a model called male_01. A normal model (from the workshop or somewhere else) includes a reference to edit from (I'm pretty sure?), however, that male_01_reference.smd file isn't included when I decompile male_01.
Anyone know what's up, and if there is no reference, where can I get one for the stock playermodels?

Are you using GCFScape to get them? They should be there, maybe they're named as LOD despite being the actual reference model.
