Finally got the mystery racket in and it's a beauty in great shape:
All i know is that it's from the same mold as the Pernfors, it's high-gloss black with yellow sprinkles and silver accents. The silver has been dripped on it, so it's a kind of 3d layer on top of the rest. I especially like the "Anniversary" text on the bridge and the side of the throat which is candy pink with a yellow dropshadow (hello 80's)(my camera won't even capture it in all it's clashing technicolour).
I think it still has the original grip and factory strings, very aged and cracked Snauwaert MultiControl.
Anyone have some more details about this and/or the specs from the original Pernfors frame for comparison?
