Thank you so much for replying and also for asking for a pic of the other mark - when polishing the apple caddy I found an additional mark - it looks easier to identify and possibly Japanese like you thought.
The first pic is a similar mark to the leaf's on the side of the apple - the second pic is the mark on the apple base. The apple top is hammered silver unlike the leaf but the leaf texture and stem are identical. I'm pretty certain it's the same maker.
Thank you for trying!
