I haven't been in to Parkers more than a couple of years, but I've had an interest in vintage guns for a long time. I think I can honestly say I have never seen an 80 percent Parker on the open market outside of a Julia's auction. I'll even go so far to say you probably cannot find one for sale on the internet. There might be one or two that can be found at one of the more exclusive gun shops. What is even more rare than the gun is the person who is knowledgeable enough to accurately place condition at 80%, AND, pays the money to acquire that condition, but who would then be foolish enough to install choke tubes. That's the real head shaker to me. My guess would be the choke tubes were the second mistake.

On a side note, I've seen a lot of 80% refinished guns. Those are usually grossly overvalued.
