I could not be bothered to read past the end of page 2. But practically every response was wrong. That bypass bar is a "proper job" and was used extensively by the gas Board / British Gas to relocate meters to the inside when a coin meter was fitted. It is not impossible that someone has obtained one, and is using it ilegally, but only a moron would do it so visibly, implying that it is a legal reposition. There are, of course, dodgy ones available on Flea bay, but most are constructed from fittings.
