....In terms of that yearly tax, back around 2008 Spain imposed a new, yearly, tax of 100 Euro on each gun possessed. This tax flushed out all the shotguns held, but infrequently (or never) used. Rather than pay the 100 EU yearly tax people just turned them into the Civil Guard....
Well heck, this is enlightening. One way to look at the weak market value of used Spanish doubles is that a whole lot more folks could be introduced them. Later, they are the folks who might seek out a higher end gun, just as the folks who can afford it, started at one time.
I wonder why there's such a push in the US to flush everything out of the woodwork and get 'em registered.
