Schempp Hirth interior grey - paint match

Looking to touch up the interior of my early 80's Nimbus and have been searching for that "just right" grey color in a rattle can (USA market). I've looked at Krylon, Rustoleum and Valspar. So far the Valspar "smoke infusion" color (85039) is closest, but it's still a bit on the light side. Anyone found the perfect match?

I can always go to my local industrial paint supplier and get a can of matched lacquer / enamel, but would rather avoid having to get out the spray equipment each time I want to do a part.

Thanks,
Craig
