Mint Julep nailed it. It's an original cap box. It had the small 39 cartridge box plate on it at one time. I'm not sure of the true history of these, but I suspect the box plate was a Bannerman addition. Though it's original, it's not an item I'd buy for my CW leather gear collection, namely due to condition plus the plate addition. The plate would add considerable value just for what the plate is. As is I'd be surprised if a retailer could fetch $75 for it. Decent condition boxes of this type go for $125ish, (no interior wool), up to $250 in excellent condition with all interior components.
