would anyone be kind enough to tell me if they know of a supplier for

one for a present for a friend.

thanks in advance

Pop black hamburgh and then black hamburg into Google's search

old-fashioned one, but some still use it. I imagine some of those
suppliers may have container-grown ones ready to go.
