As far as federal law is concerned, if a gun is 50 years old, or more, it's C&R, so anything made prior to today's date in 1967, or earlier, or can be shipped to a Type 3 C&R FFL holder. But apparently Washington state law, such as mentioned above, trumps federal law. I've never read it, but a Type 3 FFL holder has to log acquisitions and dispositions in a bound book just as any other FFL holder, so it seems the Type 3 FFL could just make the WA required background check call, unless WA law or BATFE says otherwise.
I purchase several C&R guns every year, so it's well worth the $30 every three years for me, rather than paying an additional $25 per transfer to my friendly neighborhood Type 1 FFL holder.

Early Remington M700's, Winchester M70's, Weatherby's, and a host of handguns are C&R eligible under the 50+ year regulation. Fifty years wasn't that long ago...
