Sorry no pics, very easy to make and not much to them. If you go by Monahans in Weymouth he may still have a few of them for sale...
As for lead flashing, plumbers lead is excellant almost pure. I think all lead has some nickel or tin in you want the "soft" lead for pouring especially large amounts. I have used line-o-type but it is "hard" and not as heavy by volume. Always pour outside and try not to breath the fumes and absolutly NO Water around!
