Researcher-all parts match the 350, 360, and 370 models. The ads above show the main differences appear to be barrel type i.e. twisted, damascus, and special high pressured steel. My barrels do not have any barrel type on them so would it be correct to think "twist" and "Damascus" would be so marked on the barrels?

Thanks

P.S. I believe your user name is the most appropriate on the gun forums that I look at. Your research is greatly appreciated and some times the only source I've received on other firearms info.
