tea set

[AngusAardvark]

I've found the following with various items I have inherited recently.

They don't actually look like a set since the patterns are different but they were all together.

I can't find any marks on them.

So I am wondering;
1. if marks are hidden in any standard places other than obviously on the bottom or the sides
2. if they are massed produced silverware from somewhere and therefore would not have marks



This closeup of the inside of the lid looks machined



any help appreciated.
