(I do like the Red Baron Gretsch but those are all quite made by someone with a bad taste)

Looks like a prop from Iron Sky.
I'm no shrinking violet when it comes to Nazi humor, but I wouldn't want to be caught playing that (never mind that it would be a criminal offense in Germany to do so, depiction of Third Reich symbols outside of historic context is a criminal felony in Germany).
I know what the guy advertising this is aiming at though, I don't think this is made for up and rising Nazi bands but more for the guys looking for an ultimate shock effect, could envisage this with a Brit glam or Japanese manga style band. Good taste it isn't and probably not meant to be. It's saving grace is that the Nazis themselves were very particular about their symbols being used and would not have approved of the relic job at all. This would have seen you off to the
Lager for an educational stay very promptly, jawohl.
Taste questions aside, I don't think this is political. When Jimmy Page wore his Luftwaffe hat with the swastika, Scott Weiland his SS cap with Velvet Revolver (scrapping it when he caught, pun intended, flak because of it and donning a Russian officer's cap from then on), when the Sex Pistols sang/punned, albeit historically inaccurately, "Belsen was a gas" (there were no gas chambers in Bergen-Belsen, people died of starvation and rampaging diseases there), when the Thin White Duke gave his Nazi salute or when Ace Frehley had the fine humor of surprising his son-of-an-Auschwitz survivor bandmate Chaim drunk in an SS uniform in the middle of the night during a Japanese tour, none of them were advocating Nazism as a political ideology. Whether you think it's funny or necessary is another matter.
I believe we will see more of this in the future though as the generation who experienced/suffered under Nazism dies off and those generations that followed - like us - become older too. To an 18 year old today, Nazi horror is more likely than not an abstract thing. That doesn't mean that these people are then Nazis or sympathetic to the Nazi cause, I firmly believe that as an ideology Nazism - except for those utterly depraved in intelligence and/or character - is forever tainted and discarded on the scap heap of history. (Any comparison of dictatorial or racist regimes today with Nazism as it was are always inherently flawed and unhelpful from a political analysis view.)
