I'm looking for the conversion matches the RODEN's paint codes :
1401 , 178 9 and 2073 in Humbrol references
Thanks fot help.

The numbers could be references to Testor/Model Master:

http://www.flashie.nl/A/modelmaster.html
1401 Aluminium Plate Metalizer
1789 Airbrush Thinner ??
2073 Rot (Red) RLM:23

http://www.humbrol.com/convert-to-humbrol/?
But this tool could not find matches Testor -> Humbrol for these three numbers.
