I just assumed that once the specs were estanblished then there would be a model number assigned to the Heyboer part or whatever co makes the eventual piece. Regarding the misogyny charge; I can't help it, most of the women I know sigh like that but I don't know any men who do. Thats just my experience and after all we are only the sum of our experience and that is all we can really ever know. I don't see it as a criticism of women that they sigh; I just compared what I know to be true with the circumstances.
