Hi Ubaranda -
Jacobsohn, Cal Herman, 1863-1873 (!)
I have a little saltspoon from him - assayed 1874 (!). A. Leistikow used the mark and dates from Vilite. Seems that original marks from him are rare, dates unclear. His output must have been not very large - you see his silver very seldom.


If CHI is also Jacobsohn, C. H. - why should he change his mark?
I am confused!
Anyway many thanks for your efforts!
Regards
Goldstein
