Bosun has pointed out and I think correctly that traditionally anchors were made from steels, sometimes, possibly not even as good as Q420. I am pretty sure there are anchors sitting in chandlers today made simply from mild steel, these will all be cheap and unbranded. However many of these anchors will have very thick shanks, unlike modern anchors like the Supreme, Excel and Rocna. There is nothing inherently wrong with building anchors from a steel like 420. Unfortunately thick shanks contributes to poor perfomance (which is the reason there has been the move to thinner shanks). The problem arises when the design allowed the shank to be very thin, because the designer specified a high tensile steel, but the manufacturer uses a lower quality product. It is possible some of those cheap and cheerful unbranded anchors are safer with their thick shanks than the expensive 420 and thin shanked Rocna (though I would not use either).
I might also agree with Vyv Cox with regard to the centre punch test. I had never gone through the exercise before but Bis80 is basically impossible to mark, you scratch the gal but no more. With galvanised mild steel the centre punch can almost stand in its own indent. 420 comes somewhere in between. It might be more difficult to categorically tell 620 from Bis 80 (but that is not the issue) and I do not have a peice of 620. If the galvanising is an issue, file some of it off - its not difficult, then paint it (that's what Rocna did with gal blemishes, simply painted the offending marks).
As to how many Q420 shanked anchors were made and sold, Mr Bambury will know, he will also know to which markets they went and when they were sold. I recall he works for a company claiming high integrity with customer care and attention at the forefront of their strategy and a stated policy of indentifying, and possibly replacing?, all out of spec anchors. Statements and policies are cheap - action looks almost non-existent.
CMP must know that their continued inactivity is damaging them, their traditional brands and doing nothing for Rocna. Their employment of Mr Bambury looks questionable particularly as they have not used the employment to be open about the extent of the deceit. I for one would not buy chain from them - because I now, based on their activity since taking on the Rocna licence, simply do not trust them and there are many other sources.
