Since I am a model maker in real life of jewelry I was looking to make a kr2-s pendant for myself. I had already made a p51d pendant a long time ago as pendant, as I love that baby. Anyway I actually reversed engineered that model into the kr2-s. I know it is not the same but many people look at my pendant and ask me if it was a p51 b model. I would also think reverse engineering the kr2-s would be an interesting Idea. Hmm?, Maybe it will be my next experimental after I finish this kr2-s. Dreams are what life is made of anyway.
