This morning when I showed up to morning roll call, I was surprised to see a Fedora hanging on the thermostat! I immediately went and picked it up and it was a Penneny's Marathon. I asked those close by where it came from and apparently the shift before mine did some training on auto extrication with a couple of junkers from the local salvage yard. The hat was found inside one of the vehicles. Nobody wanted it so I claimed it for myself. It's dirty and the sweat band is brittle and coming apart where it's sewn in but it's pretty sound beyond that. Any idea when it was made? I'm guessing '60's but what do I know? It's a 7 1/2 and fits well. Also, any advice on cleaning and shaping? I don't have any experience in either. Oh, would this be beaver or wool? It's seems pretty like it's pretty resilient. Any help is greatly appreciated. Here's some pics. It was found in the van.
