Junk Sale Find...Curious as to a date or any information...

I was at a local "Junk Sale" over the weekend and found this, what i believe to be a steamer trunk. It has a lift out tray inside and a gray and off white striped interior, and the only identifying information I see is what I believe to be the key number stamped on the lock which is "g22". I was just curious if anyone might know of any information on this like maybe time period, brand, how to get a replacement key and so on, anything would be much appreciated. I am not looking to get any type of appraisal for resale or anything, I make jewlery and I got it as a gift to store my supplies. Once again thank you in advance and ant information would be appreciated.
