A coupla more thoughts.
A case needs to have a manufacturer's tag on it? What the hell for? What unicorn-lover dreamed up this requirement, and what brand of white wine was s/he drinking? I want a
name,, man, a
name!
Holy cow, for casual use, I sometimes make my own cases out of canvas just to keep the dust off of them. Would I have to put a tag on them saying, "Manufactured by Terry, 230RN, Golden CO, USA, Earth?"
Here's one I made for a small auto with a mag pouch in it . The ruler's for scaling, and it's closed with a long shoelace sewn into it:

Here's the aforementioned range bag;

On the (freshly-vacuumed

) floor, l to r:
Staple gun painted blaze orange to distinguish it from some ranges' staplers --don't ask how come
Pack of earplugs
Visine
Masking tape
Sight blacking
Electronic earmuffs
Removed from the outside pouch for visibility, l to r:
Handi-talkie (I got rid of my cell phone months ago, since I can dial out through the local 2M repeater. I don't know why I didn't think of this $450 ago (at $15 per month for cell phone service.)
Bore light
Two black ball point pens
Magic markers
Inside the bag, I usually carry ramrods for the guns I will shoot that day and other sundries. I
usually have plenty of room in there for that range session's ammo. If not, I put excess ammo in yet another thrift store bag.
Here's what I carry my evil, deadly, good-for-only one-thing handguns in:

This innocuous grocery store bag with a hard plastic bottom contains three guns in (yes) hard cases even now as you look at it.

Rifles, if I haven't smuggled them out to the car in the dark of the previous night, I sometimes carry out to the car in curtain rod boxes. Which are plainly and clearly labeled "Sears Curtain Rods" ... or whatever brand they were. In broad daylight, right there in front of G-d and everyone else "to whom it may concern."
