Just out of curiosity can anyone explain what the letter codes are after the model # of a Bigsby? Just received my new G6120-DCH-LTD and it came with a B6CBVF. C - Chrome B - ? V - Vintage ? F - Flat arm. It does not have a V-cut so I am guessing on the Vintage designation, I have no idea on the B. The body does not have the black paint on it. Thanks for the help.
