Hi there,
Sorry, that i didn't respond.
After the first clueless responses, I just thought that this will stay a unsolved mystery.
Maybe i have given to less input.
I am in miniature casting myself and as far as i can tell this looks quite professional and not like some cheap knockoff.
I have 2 of those miniatures and as they are identical, and quite good quality, i thought they are part of a bigger miniature line/run.
This are onepiece miniatures with a lot of details, ( sorry my cam does not show them properly) and many undercuts.
