Do you think these are Ambrico egg cups?

They are like other Ambrico stuff i have had and are flawed in that they are not completely the same thickness and one has a firing flaw. One is crazed but they do appear to be old.
Cheers for any thoughts.

I have quite a bit of strw-coloured Ambrico tableware now, including a jug, various cups, saucers and plates, as well as a shaving mug and chamber pots in two sizes, so I have seen and handled a fair bit.

Ev said to hold off calling the jug Ambrico until I had better information then I found a match for it at Auckland Museum. Warning here: they do occasionally make mistakes.

On tm recently I saw step-sided eggcup that was called either Paris or Ambrico (can't find it now) and was sceptical about the attribution.

I have not seen Ambrico eggcups before but these do look like Ambrico from your photos and description.

Let's see what others have to say.

Its hard to be sure but they look the right shape to me....
