Hi. I have an Edwardian house and i need to re do the front bay window. At some point the 2 stone/brick pillars supporting the bay were removed as well as the stone sill itself. Look's like the double glazing has an internal metal rod inside supporting the stone at the top. (hope I've described correctly) Looks terrible. Some of my neighbours homes have the original decorative cast iron supports rather than the stone pillars which is what im after. My question is what are they called and where do i get them?
