This is very simple, high poly 3d model of cannon based of popular German cannon from Great War : 7.7 cm Feldkanone 96 neuer Art (7.7 cm FK 96 n.A.) https://en.wikipedia.org/wiki/7.7_cm_FK_96_n.A.Its not 100 % accurate because some of details were hard to identify. Texture 4096 x 4096, PBR material. Best is to open it with Blender. Create folder, unpack all to this folder ... Blender format should read textures from tex folder. Blender format also contains layers, where one layer is just cannon so you can change its possition. There are 3 separated textures for gun, shield, and suspension. So i decided to pack obj files as 3 separated obj where every have same name as texture. This way you will have no problem with finding which texture suit which element, just you need to import all of them. The model is not created for printing and its not market as printable ! If you want to print it you must have knowledge how to prepare it !
