Not trusting my poor nose, I went looking for other testing methods. I noted on an Australian site they sell a paper test strip for testing H2s in wine. In Us or Canada, however I could not find a dedicated strip. The strips themselves are nothing more than a lead acetate impregnated paper strip.
The closest thing I could find was a similar paper designed to test H2S in water, sewer,etc. at Hach Canada. Today, I ordered their Hydrogen Sulfide Test Kit, Model HS-C. This post will be updated after I have trialed it. I have dealt with this company a few times and found them very friendly and helpful.
