I picked this up for $70, with the intent of restoring it. Condition: 4-5 coats of paint ( red, blue, silver, brown,green) rust bleeding through and not heavily pitted, but missing a fin. Fin can be easily reproduced ( 0.065" thick). I plan to sand blast it and repaint to the original brown. My question, is it worth the time and money? What would the market value be for a restored MK 3?. Reviewing past posts, would $300 be in the ball park? All comments welcomed.
