Hello, i was messing about making new textures of Dalek Mod TARDISes, and i want to add back "Police Box" and "Police Telephone For Free Use ..." signs. But i discovered, that these signs were not in one, complete texture with police box, they were separately from box texture, with their own model. This thing was removed in update 60 and police box texture is now one image, one model. So, the thing is, how can i open and edit current police boxes and in what editor and how to add these two signs back? I tried Blockbench with Bug's MDL (If you don't know what is MDL  file, it's a storage file made by John, in which is model, texture, and it's properties .json) plugins, but it didn't work. Thanks for any help!

I'm also trying to figure out how to open Dalek Mod models, except I'm trying to do it in Blender, but now that I know that apparently this type of .mdl file was made by John I see that may be impossible 

 ok so never mind I immediately figured it out after posting that, you just open the .MDL files with either 7zip or WinRAR and/or just rename them to .zip 

Thanks for reply! I already discovered, that .MDL file can be unzipped and searched for files. I want to add signs "PUBLIC CALL" and "POLICE TELEPHONE etc.." but i don't know what to do. How can i add these signs back as texture, and if not as texture, but as any other file, in which program and how can i do it?

 haxer!! haxing the gayme file
