Congratulations Keith,
This is the
ONLY one of these I have ever seen. I didn't even know what it was supposed to look like before your photo.
A mould/mold (? spelling) could be made fairly easily, and others produced for sure. As to who, I know not. You wouldn't want to see this damaged by amateur attempt.
If you ever get to that stage & are considering making them for sale, I would take 2 straight away.
Think on
