No, not painted,,,patinated !! Its a chemical process that darkens brass items !! If the white you see inside appears to be on the surface,, it could be a chemical reaction from the patination process !! The outside would have been cleaned pretty well but the inside is often overlooked !! Wait till some of the other members give their opinion on your items !!
Need more than one opinion !!
Well,, if you didn`t pay a lot for them,,and you like them,,I wouldn`t really care if real or not !! If you intend to sell them !! Its not a good risk buying unknown unless they are dirt cheap so you don`t lose much !! Sometimes it really doesn`t matter,, people will buy them anyway !! You can not outguess the buying public !!
