Note: I've seen "counterfeits" even in marked Amphenol bags. Likely from China. They do an amazing job of copying logos, printing, everything. The only way I could tell one batch of connectors were counterfeit is by taking them to my jeweler and having him do an acid test on the silver plating (which sure "looked" like silver plating!), to determine there wasn't any silver content. The plating was something else, but the appearance was very good.
