Nice @ the OP. I had a chance on one a few years ago, think about 3 years ago, for ~$3500. I am sure if I gave the fella the money, and he sold it, he wouldn't be happy, so we just enjoyed our shared hobby and I told him to hang on to it. No idea what value they are, but always thought it was cool.
John/Paladin,
Can you please grace us with your collective photo on these guns? The one where you have every --just about--variant present? I'd like to kindly share with the wife to show her I am not as bad as you; and that you have been a bad influence.....
