I don't remember how long it's been since the info was discovered, but I bought mine over 3 years ago.
The correct variation is super rare. I think there are only a couple on the board. No idea what price they'd bring.
Adamata might have been the first to find a 2 1/2 and he sells resin copies. The windage knob base on his is slightly inaccurate though.
Quite a price jump on the 4x31 from $75 to $482.77.
Maybe it's time to list my spare 4x31 on eBay.
Wrong! I was the one, who found the 2 1/2 on ebay but due to a sellers mistake (it was a BIN auction), it was sold/ shipped to Tony, even if I sent payment first. It´s not Tony, who´s to blame but this stupid ebay-seller.....ah well, a bitter memory every time these pictures pop up
Found another 2 1/2 a few years later.
WOW...$482+???
Guess I got lucky to buy my last one for $100 inc. s&h a few days ago
