I am very happy I have my readily available sealed beam units in US specification, with intact reflectors and replacable for less than $10 at any auto parts store, Wal Mart, Sears, Canadian Tire....and the "doors", even though they are pricy at near $300, are still available.
When somebody finds a nice set of that Euro glass, somebody ought to use the lenses as models and cast a set in polycarbonate.
