If you are asking if the first weapon I posted was a 66 which is basically the stainless version of the model 19 K frame , no , it was the slightly larger L frame 686 which is the stainless version of the 586 .
The weapon I am attempting to post here is the 66 . They look enough alike they could fool someone that owns them both except the 686 has the full length ejector rod shroud .
