A buddy of mine and avid lens collector once mentioned the credo of all collectors: "everything comes to him, who can wait long enough...". Well, I must have waited long enough, since after some years, the brothers finally found each other..

Of course I had to test them, although the 60mm and 105mm have never been used before, MINT in makers box. About 25 or so have ever been made of these I was told decades ago.
These were made once to transmit from about 300nm (UV-A) to the visible range and are color corrected from 350-546nm (no focus shift).
I use them as taking lenses for my UV photography.
Hardly anyones knows about their existence...
