This is Albrecht's 2-axle third class coach of the Prussian Sate Railways, and it is 1890's vintage. It is available from Albrecht or as a free download. There are no instructions but the build is quite straight forward. I am building it to go with the Durchbrenner, and I intend to pick the first class coach also. I have already cut out and edge colored the the parts so this should go quickly. I just need to fabricate components and then assembly. here are some initial photos. Note that the wheels, bearing boxes, and the floor of the coach are all laminated with .5mm card, as taught by the great Wanni :D. the goal is to get everything aligned straight and true. Herr Pirling's design is very precise, any errors are mine.
Edit: Fred, sorry but I removed picture 2. The printed signum of another "forum" is banned in this forum. Please remove the upper part of the picture. I trust that the redacted picture is now acceptable.
