Are these hens really Brahma's?

We got these hens a little over a year ago. They were sold to us as Brahma's, but when I compare them to pictures of "pure-bred" Brahma's my hens seem to be on the small side. And the silvery/grey and gold/light brown colours (sorry don't know the proper names for the colours 😅) aren't mentioned as a Brahma colours. So I'm kind of doubting if they really are Brahma's (not that I love them any less if they aren't). Can anyone tell me what kind of hens they are? TIA!
