I'm always adding to this kit, and you're guaranteed to receive all future updates.
If you are looking for a high quality hard surface kit modeled by a VFX hard surface veteran, look no further. Every mesh has clean optimized UVs and quad subD topology with support loops. This kit as it stands could sell for well over 250$.
Unfortunately due to the size of the kit I can't truly showcase the detail added to these models. Please see the topology examples in the images to see closeup examples. This level of quality is consistent throughout the entire kit.
Included in this kit:
Bolts/Units, Brackets, Caps/Inserts, Circular Details, Decals, Engines Parts, Hinges, Hydraulics, Misc (general), Pipe Details, Pipe Flanges, Pipe Fittings, General Pipes, Welds and more.
All models have been organized into an asset library for easy access:
I've made sure that all rounded geometry has been given enough resolution so the subD models can be decimated down into lowpoly game assets in seconds using Blenders decimation modifier set to "planar" combined with a triangular modifier if needed. 
Enjoy!
