During his early working years, he wrote his labels by hand. As early as 1863, he began to use printed labels. New labels were ordered in 1871 with larger letters and were mistakenly printed with "Samueli". In some cases he erased the extra 'i', but on some, he left it as it was. On occasion, Nemessányi was known to use the brand mark of "N S". In faked violins, there almost always exists a brand mark, even though Nemessányi barely used it in his own instruments.
