Hi Dave,
Afraid I can't tell you much about it, except it came to me via a serial airgun owner who flits from one thing to another, buying guns from all over the place, often on a daily basis!
I later traded it with Chris (a nice bloke to deal with
).
If it helps, I've looked up my original (no pun intended!) 'for sale' thread from a couple of years ago:

And a valuation thread that Chris posted later:
http://www.airgunbbs.com/showthread....300r-valuation
should never have sold my other one but needed
So, what's your next Diana going to be then?? (open question to anybody!)
