I have a client that loves the font that Callaway Golf uses as seen here. He's real particular of matching this font. I went to www.whatthefont.com and www.identifont.com and a variety of other websites but was unsuccessful.
You see the little (R) thing - that usually tells me it's not going to be easy to copy elements of their brand and legally trademark it - especially if your client is in the golf industry. I'd have the client pick another font and not try to match it as precisely as possible. It's very likely a custom calligraphy anyway. Their mark is pretty much just relying on the typography save for the little geometric golf tee artwork below it.
Remember that some old companies like that, are probably using a custom font. Many years ago, their designer created their logo, and possibly created the type style from scratch. There might not be an exact match anywhere.
Tell the client that it is a trademarked, propriatary font, and that you don't intend to violate the copyright laws.
You should allow access to the cumulative results for those who've completed the survey. If someone takes the time out to do a lengthy survey with a lot of thought involved, there should be some pay off...
