I can second Pete's recommendation of Cecil Fredi. Especially if you have reason to be in Las Vegas. I have to go to Vegas twice a year on business and I'd much rather look at wood than gamble. Cecil's a great guy. If you do go visit Cecil, ask him about his adventures in Africa.
I'm reading this thread with interest because I am thinking about a project gun as well. Like many others, it's a Fox Sterlingworth 16 gauge ejector, Utica gun from 1935. I'm hung up on whether or not to rebate the frame as done on higher grade fox guns.
