Beantown, Im sorry, I dont. Your actually the second person to ask me that in the last week. Ive personally never seen one, but my coworker was telling me how he passed on one once because he said it was a port hole style, but the front number were sewn, while the back and sides were screen print. I think.thats cool, but because it didnt have any prominence he found it to be too odd/fishy to pay what the seller was asking. I got the impression it was years ago though, and there wasnt the resources that there are now a days to research it.
