Why, yes I have seen one.
In fact, the last time was when I opened my safe!
Extremely high quality, absolutley great trigger, superbly accurate (mine's in 30 Herrett) and it uses TC scope mount rail. Other than that, I have nothing good to say about it, except that I bought mine at my friends shop from a personal collection for the grand total of a price I'm too embarassed to share!
I say buy it!! The only real disadvantage I see is that the tubes are not interchangable, but it does give you a fine piece to learn about accuracy. Enjoy!! Gerry
