Dad just dug out of a trunk an RAAF hat he got in New Guinea. Traded something for it with an Aussie friend. The hat is crushed, but I think it is all there; it still has the RAAF medallion. He thinks it could be refurbished and he could wear it again. He probably hasn't worn it since the 40's. Who refurbishes these hats? How good are they? He does not have a lot of money so how much does it costs? Any other advice you care to share will be greatly appreciated. To be clear, the hat is in the USA.
