There is a lot more still to add on this when I have time. There is strong evidence to question some of these dates.

It looks as though you are backtracking also.
You state "But in truth it is definitely not certain when arrowdies were first made, whether it be in 1951 or 1946 for that matter."
Earlier you seemed absolutely certain.

Back to the VS. I also found this interesting. I went back to look at that first attribution, and found it to be in Doug's Chip-Chat Bruce Landau auction on 14 June 2004.
This is the part I found interesting - despite the prices John Benedict claimed they previously changed hands for, and that this was potentially a big new discovery, and that some incredible prices were paid for other chips in that same auction, the hammer price was only $85. IMO that was a good indication collectors doubted the attribution straight away.
I also note that since then there have been a number of ebay sales, with an average price of just $50, and with two that had starting prices of $50 & $60 receiving no bids. The last two examples I saw earlier this year, while we were editing TCR, fetched $31 & $21 respectively.
