Hi,I have an older home with 2 X 8 quarter log siding. It measures 1 1/2” max thickness X 7 1/4” overall length, with about 1 3/4” flat ”reveal” in between boards when installed. It is a shiplap style, not a tongue in groove. Where in the world can a find a replacement siding to match? I need to do some repairs, as time and the elements have taken their toll on this old house! Thank You!!!
