Hi Gordon,
This company specializes in manufacturing pewter items of the finest quality with high detail.
Items such as giftware, souvenirs and pewter promotional products.
Corkscrews, ornaments, lapel pins, money clips, custom key chains, even coffee mugs with the pewter item attached, etc. are available
They have an artist who will work with you named Norman Fortin who will hand carve your model and make your design a work of art.
His most recent piece was a portrait of James Cameron, the director of the movie Titanic.
You can check out their custom gallery on the website.
I think that a medallion would be great for your purposes. Someone could carry it in their pocket or could even have it made into a necklace, money clip or lapel pin. That would be a very versatile way to go.
I'll do some more digging through my files and if I can find more manufacturers, I'll forward them on to you later.
Good idea Gordon!
Best Wishes,
Amber
