Thank you That helps me a lot Just one sentence needs some adjustment In 1963 it was discovered that 206 paintings had been destroyed and 507 were missing This change does not sound correct to me because it was not discovered at this time it has been known before Actually the gallery published a catalogue of missing and destroyed paintings of the old and new masters in 1963 from which these numbers are That s why I wrote 206 destroyed und 507 missing paintings were accounted for in 1963 Could we correct this somehow Thanks again I really appreciate your help
