This model is Door handle parts from Buster and Punch. please see the main product via this link: https://www.busterandpunch.com/hardware/door-hardware

there are 3 different locks that you can use in case of your project; all the materials are PBR and have textures; there are 3 different material in the scene: Brass, Silver, Steel there is an extra map in the archive named: HandleHeightDisplacement.png in case of need to use displacements; I modelled this handles carefully with clean topology; the door handles has enough detail for close-up renders; you can use it for modern scenes;

Sincerely, Shirbeigi
