I have a dog old Daina (of Germany), with a Weaver base and a Simmons Blazer 4-12x  40mm AO (it is holding up after 3 years).  My German in-laws bought it in 1974, I found it in a shed rusted and neglected.  I cleaned her up.
Until my German neibors (what else would I have here?) complained, I used to shoot in the yard for hours on end, now I have to go to a REAL SHOOTING RANGE, yes I said a range!
 
It's a stupid air rifle!  Who ever knocked off a bank with an air rifle?  The Germans are starting to controll  airguns like rifles....Aaaaaaaaaaaaaaaaugh!
Oh well, tha Diana (one each, old as mud) is a superb airgun, id you could find one in US, I promise you'll like it, just don't use it IN Germany
