He's apparently a dealer and has to resell it. Judging by the 14 pages of other items he has bought recently, he is not a shotgun person. One thing the 14 pages proves, he has plenty of money and a heck of a building to put his stuff in.

I think that is a lot of it. A dealer knows that there is money in some Parkers so they figure they can't go wrong. At the last local gun show I had a guy show me a Trojan that had a lot of issues and wanted me to make an offer. I did not want to at first and I told him so. After telling me I would not hurt his feelings I offered him my price and of course he didn't like it. Believe me... It was an appropriate offer for the amount of work would have been needed to be done on the gun to make it right.
Anyway, the next morning, I saw it sitting on another dealers table. I can only imagine what was paid for it.

Well, we all know that dealers are also some of the most prestigious collectors, too, so it is possible the gun was bought for his private collection.
