Just a note of caution for those of who like to play, take apart, and clean older brass lenses - many *may* contain lead paint. While testing some other products for lead content I casually tested a few lenses I own and rougly 1/3 contained lead in the black paint that is used internally on these lenses, inside the lens hoods and on the reverse of many flanges. The worst offender was an 1860 CC Harrison lens... Almost all Darlot lenses did NOT contain lead.... just a note of caution....
