Hello I found this civil war era two headed snake buckle the other day. ....HH.... 401K .... Update.... This type of snake-duck head, seems to be the early verity. It seems the closest match that I have seen is an early English version. I'm thinking that it could have been used in the 1700s and possibly in the Rev War on an English military uniform. http://www.google.com/url?sa=t&rct=j&q=http%3A%2F%2Fwww.colchestertreasurehunting.co.uk%2Fs%2Fsnakebuckles.htm&source=web&cd=1&sqi=2&ved=0CFIQFjAA&url=http%3A%2F%2Fwww.colchestertreasurehunting.co.uk%2Fs%2Fsnakebuckles.htm&ei=L-C9T8GxGPG16AHJ2MlE&usg=AFQjCNEQqNL0b75k_ZMUjAmiIJ8ENh1TUA&cad=rja
