It's the Dragon kit, sans PE, reboxed by Revell.
It's a great kit! Lucky thing, too, since it's the only decent 1/35 kit out (not counting Tamiya's ancient collector's item and the old Nichimo crapper).
Two versions from Dragon: Henschel and Porsche suspension. I have the Porsche kit.
Great kit!
I always thought "spritzpistole" was interesting, too!
