OK this one is totally off the wall. I am working with a business called Radial. Over the course of the last six years certain members of that firm have gone above and beyond and deserve recognition. I was thinking maybe giving them clean parts from a radial engine as part of an award ceremony. Such as a piston. Obviously it will come with a more practical $$$ award as well. Can someone point me in the direction of an authentic but reasonably priced priced part of a radial engine that might be suitable? Thanks.
