Metal Stool decade request

First, let me apologize for not having the dimensions. My water tank burst
and this metal stool was thrown away by the mitigation company because of water damage before I could take dimension and they did not take dimensions either. This is the only picture that mitigation company took. My insurance company has asked me to assign dates to pictures of water damaged items and to submit them for insurance claim. So, I would like to ask what decade do you think this metal stool could be from. This metal stool was used in a hay barn that was 1/3rd portioned into my dad's woodshop. The metal stool was found in the hay barn upstairs in the loft and brought down for my dad's woodshop bench area. Thank you for assistance in this request. Regards, Rob
