Oshkosh Inside BAR LOCKING footlocker

[excalibr]

I had this listed in the WWI forum section, but maybe it should have been in the WWII forum section. I bought this at a local estate auction. I bought it thinking it was a WWII footlocker. BUT....the more I look into it I think it is a WWI footlocker. The last patent date on the Oshkosh label is Oct 31, 1916. It is in great shape. It is named with company and other info. The inside tray and inside lining is great. I'm just looking to see 1: is it WWI or WWII? 2: is it a rare trunk? and any other info I can get. Thanks!
