Sadly it's everywhere
Got our gas fire serviced - it was condemned and we were told the parts no longer existed
I found the part after 5min Google search
They came back - was told it was the wrong part and was told to contact the manufacturer and find the part myself !!!
Gas engineer's office did not want to help find the part, just said it didn't exist.
So i called another company who said we had the correct part all along and fitted it within 5mins
