I was cleaning my Cogswell and Harrison very many years ago, back in England, and my girlfriend was watching me. I put some Youngs 303 on a cloth, she sniffed and said "dab some of that behind your ears and I'll follow you anywhere!"
Nothing smells as good as 303 solvent, sometimes you can open the 100 year old oak and leather case and the nice smell of Young's will drift out.
