I have a really old Tappin gas dual oven, oven on top and broiler on bottom, I think maybe 1971, But I'm not sure.. the pilot light is lit, but right after the pilot light is a long metal peice that won't light... I am trying to find out information on this oven so that I can order parts, but the numbers I have from the door of the oven are not recognized by anyone.. Can Anyone help???
