In the topic "Unknown maker from Riga" Ubaranda says
In 1891 he was only 17 years old ..., meaning he was too young to make those spoons.
I share his opinion, which reminded me of a nagging tought that I have had for some time.
This chalice is attributed to the most famous silversmith of my town (18 century).

It's very simple, actually, but, according to the date, he would have made it at the age of 14.
This does not convince me at all. Even assuming he was a wunderkind, what teacher would have made available to a little boy all the equipment needed to build a chalice?
Which assayer would have affixed the city mark and his own on an object presented by a boy not registered with the guild?
I'd like to hear your views.
