The "hooks" instead rivets under the liner
cannot be accepted as a general rule.Depends on silversmith`s preference Hooks are easier to make but need longer prongs and more gold wasted. Therefore preferred with the liner in purses because the liner hides them.
On the other hand,bent hooks in cigarette cases are not acceptable for obvious reasons.
Btw.
Aрбетманъ family name ending with obsolete letter cannot be found any more and counterfeiting it makes no sense.
Not profitable in this case even by Chinese.It`s extremely difficult to cut it and a lot of gold wasted for no profit.
