When a 42 goes bad you might get as well throw it away. Send it to me, Ill take care of it. Seriously what exactly is the issue. I run a small stable if 42s and might be able to direct you to the right person depending on what you want to have done. Often there are two problems with 42s. 60 plus years of crud or worse 60 plus years of poor repairs by experts who should have both hands broken.
