Doubledecker passenger car class Bhp

My last conversion. Doubledecker car Bhp from PKP. This set was adaptation of four section car from Rivarossi in DR painting. Ends of the roofs were cutted away and in their places were glued plactic pannels. I used the putty to fill all gaps. Ttwo of three windows at head wall were removed and holes were putty.
All was little weathered (soot from steam locomotives).
Painting scheme is for V age, 90.
