Some of your figures may be correct or close, but there are more than two BHE 0000 frame .410s because I have seen more than two and popular information shows 33 with 100 more unfinished. The unfinished guns are either now finished, in progress, or still in the hands of the Skeuse family, according to what I have heard. The Sisley article cites information from the Skeuse family and is probably the best information we have. Why are you quoting Chaddick when you know he is wrong? What is your logic in saying that "I have only seen one, so there is only one, except that there may be one more."? There is no evidence that the Chaddick gun was a prototype and there is no evidence that there are any fewer BHE 0000 .410s than Sisley cites.
