Stampings

This area is for the notations about the various stampings on the briar and their locations. Again, just a start. The codifications and abbreviations are my own and ties into several charts I keep to record the differences. THE INFORMATION BELOW IS STILL UNDER CONSTRUCTION!!!

Please be patient as I find the time to update it and add photo examples.

Legend of older common stampings styles, etc., to be codified and added.
