I am looking for a set of 1:20.3 decals for a D&RGW 6000 series flatcar. Does anyone know where I might be able to buy a set?
Are you looking for dry transfer, water slide or vinyl?
For water slide I would recommend:

For vinyl:

For dry transfer CDS made the best. But I heard they went out of business. However, some train shops may have them in stock still. I have not tried these folks, in the UK, the samples on their web page look as good as the CDS:

Stan's decals are top notch! I use his for all of my work. You can't go wrong with him.
