Very nice and you might want to contact dcaptain.com (dcptain@aol.com) who has gasket material for Beacon Rays, and he may have some generic gasket material to fit this. Also Gary at rescuemarket.com has gaskets.The 'original' dome was red! QUITE the fade over the years... but lights up and motor works; I had helped an acquaintance with some vintage Whelen beacons back along, and he called and asked if I would like this ($0). Nice to be thought of...
Now to find a replacement base gasket.
