Without doubt a VERY desireable & collectible set. The only production information I have to hand is from the Kolls Guide. First there are two versions of the set, the first was made only for 3 years 1984-86 and can be identified as the Deutsche Reichsbahn lettering is >46mm<, whereas in the second set the said lettering is >39mm< and it was made for 14 years 1991-2004.
