Regarding the confusion on my hang tags:
It came to light that the original owner of my guitar bought two Springys at the same time, he said they were identical down to the color. I'm suspecting that one of them was probably a rosewood board, indicating the BBR, and one was a maple board, indicating BB. Maybe the tags got mixed up. Alternately, maybe the "R" stamp was placed accidentally that day... it would be as easy as forgetting to rotate the wheel on a rubber stamp. Maybe they didn't bother to throw the card out and start over as it wasn't really a big deal. I'm thinking that this is the more likely scenario.
My springy has the 'spaghetti' type logo. Not sure what you're referring to with the block letter thing.
Serial # in the card is 1013561.
Also on th back of the card are the numbers 430-91. Not sure what this would signify. You can see pics of my card in the "pics" thread.
Serial number on the neck plate (which I understand is meaningless) is for the record 0173
