This etch from 0.15mm brass contains parts to detail two wagons.
The uppermost edge of the rain strip is half etched to help with its location. In addition it also gives a thin appearance which scales out to 6mm full size.

Note that the majority of VDA’s that are fitted with a rain strip have the ‘shaped’ variant which is available on the link below.
Please check images of your chosen prototype for suitability.
