This is an interesting topic, great job on your grill repair Andy !
another 'hobby' i have is old Schwinn bicycles, I have been looking for a tear drop reflector for a bike thats been built from my stash. I've seen new/old stock reflectors sell for $150.00 and after market repops sell for $50.00.
I went to a garage sale and bought this girls bike for $5.00-
this is my bike before and after, took the reflector apart cleaned/polished the lens with Novus painted the housing with Dupli Color chrome
the girls bike also had the right era reflector on the rear wheel hub shiner so i replaced the luggage rack reflector too
