Made great contributions to Gmod over the years with different contents/addons.
I used parts of Half Life Renaissance weapon's code to re-create specific HL1 weapons.
Not seeking explicit permission for custom use as steam profile stats:

    "Don't add me about anything gmod-related or related to my workshop addons."

    and content says:

    "I'm done with gmod and I don't take requests, so please stop spamming the comment section.
    There won't be any updates or new packs."

And Code was non-functional as it existed.

Valve/Possible 3rd Party Modeler

Captain Charles, Shotgunguy49, CrazyChcken

Half-Life:Source HD Ported Models

For:
    - HL1 Gluon Gun model (weapon_egon)
    - HL1 Gauss Gun model (weapon_gauss)
    - HL1 Satchel model (weapon_satchel)
    - HL1 Tripmine model (weapon_tripmine)
    - HL1 Grenade model (weapon_grenade)
    - Associated viewmodels/worldmodels/textures/materials
The associated assets are not my content, and were distributed with the code for said weapons. I'm assuming the author had   
permission to use them and that they are open-source. If this is not the case I will gladly remove these assets and require HL:S for this 
content
