I have Bill! I joined day before yesterday.
I have 4 Hawkeyes on the way to me, only one is the pre-flash model though. I bought them all on eBay or Etsy. The most expensive was $15, but it's whistle clean and has an exposed roll in it.
I know that I want to keep two in original condition, but the other two I want to clean, paint, and flip the lens in.
I'm also going on an antique store run tomorrow to see how many I can find. I can't wait to get my first ones in and start shooting them!!
