I've got a pair of them that were made a few years apart. One is blued and has a 3/4 ton truck spring for a hammer spring. Hard to cock, and hard to shoot. It could use a good action job. Other than that, fit and finish is pretty good, about comparable to a 30 year old Armi SanPaolo or Pietta.
The other one has a London gray finish and virtually no markings. It was probably made earlier than the blued one. Action is smooth on it and fit and finish is real good.
Both shoot pretty close to POA at 20 yards with the gray one better than the heavy triggered blue one.
