Hi Gerhard
Darren Roberts/Steel Beach did produce a resin correction set, but it is out of stock at Sprue Bros, and likely to remain that way I fear.A few months back I emailed him to enquire about buying a few sets and he told me that he was not intending to produce any more. Adapting a Monogram nose only partially solves the issues as the lower forward fuselage / gun vent area also has issues...as well as the front windscreen.
Sorry to be the bearer of bad news.
