thanks for the comments, I'm glad you liked them
I'd like to share some details about the current markings of these wagons with you.
after all these years of service they now bear several layers of lettering and in some cases at a different position.
as there is no reference material from the 80s, 90s or earlier, I tried to figure out how they should have been at the early-mid 90s
note the different position and lettering of the later marks!
another point is the inspection-service date. although the interval is supposed to be 6 years it seems that it usually takes some longer...
so going back to model them in the 90s we'll have to use some "fictional" dates in most of the cases
unless one could lay a hand on some of the MAI archives, if there is such a thing available today
note again the different position of some of the markings
I'm going to load soon a drawing with the markings position as I think they would have been
I wonder if anybody has some older reference, any help would be most welcomed
