Not sure where we might find factory info about it. Would probably need someone in the Czech Republic to track down something like that.
I have 2 chromed DUO's, one dated '44 and one dated 50'. My thought is that they were 'bring backs' that were chromed here, just like 24's and 27's.
Of course I could be wrong. ;-)
