C.S. Snake buckle & nice IH This thread could be of some help to you. I found a buckle similar to yours, mine also looks like it has goose heads on it. Cool find!
The snake pattern buckle was used by several countries over a long period of time. That one is a beauty, and looks like an older one. Perhaps a snake buckle expert will chime in
When I lived in England folks would find these a lot. I'd have never expected one to pop up in Canada. Nope not in a million years did I expect that...great find and yup I am jealous
