Evening! A friend gave me a Crosman 66 Powermaster. I am cleaning it up and replacing seals. It is a 1st variant (zinc receiver) so 1983 -88. I am trying to figure out if the barrel shroud (if that is that right terminology) was blued, painted or powder coated. It looks blued to me, but looking for someone w/more knowledge then mine to let me know for sure. Thanks!
