The Amphicar owners club operating in 1977 decided to create 100 belt buckles and offer them to the current members with their club membership numbers on the back.
This buckle is number 014 and was purchased by Gilbert Heinrichs from Ohio.
That's interesting. I know they were made by the original US Amphicar club but didn't know when or how many. The one I have here in the UK isn't numbered.
