I have no idea what this is for exactly, but it had the magic numbers "7 1/8" on it, so I bought it for a couple bucks. Advice on what it's used for or how to, anyone? I'm assuming it has something to do with the brim, as it also says "2 3/4"
Its a flange stand and a flange. You select the flange by the numbers marked for the hat and brim size. Put the hat, crown down, thru the hole in the flange and the brim rests on the flange. A cloth or canvas would be layed over the bottom side of the brim and a spring was placed over the cloth and into the groove that is routed into the flange. Steam the cloth and brim. Then you would lower a heated sandbag down to rest on the brim for a period of time to set the brim's flanging.
That is my understanding of this equipment and brim flanging process. If any of the hatters have corrections, please feel free.
