Question about pottery on Palace maps

[Bruner]

Heya! I've been really curious about this for a while now. A lot of restorations of these Palace maps use these pot models from Counter-Strike: Source. I'd like to know if these models were present in the leak and were simply repurposed for CS:Source, (like quite a few beta elements) or if someone's really popular restoration included them, and everyone else used them for their own restorations as well.

Yes, all the models on the screenshots are in the original anon-hl2 leak, and a few more too.

You can download it here and see for yourself.

The native HLMV found in it can open the models.
Or you can even just see their jpeg previews in the models folder, they correspond with the models.
