Yep, the picture sucks. It does have the target hammer. Nice looking specimen you have there yourself.
Its a bit of a misnomer to say it was Colt's "top of the line" 357 because it was in fact the only 357 before the Python (after WWII).
But, if I understand correctly, the 357 and Trooper (in .357) were manufactured for a time before the Python was introduced.
