Nice Fishscale patterned Bunn Special, those are one of my favorites. I would look for a straightline dial and hands for a more Railroad look. But then again, that may be an original makeup.
I have never seen a Bunn Special with a dial like this and especially those moon hands. I have to agree with Steve that it appears an unlikely original match.
Mike Iam picking up another one of these this weekend. He has a lot of high end watches that he is now ready to sell. He is wanting high end prices. I'll post my second one this weekend.
