this case has been heavily modified, to make it look correct it will require a major
refit. You can look at other cases and get an idea for you layout. Single gun cases will all have some traditional layouts, barrel channel, butt stock,oil bottle, and snap cap spaces and maybe lids for compartments, more items may be used depending on space in case. I have refitted many cases and if i can answer any questions would be happy to help.
