You are looking at a Shimano Dura Ace ST-7801 (update version of the ST-7800) left shifter. It is very clean only having a few small scratches at the end of the shifter even the face plate is in good shape (many are dented). It works perfectly. The 7800 shifters set the standard for shifting smoothness and precision and  were the bench mark for shifting feel that Shimano used when designing the 9000 shifters. Thanks for looking.
