Sorry my message above doesnt belong in the skully posts. BUT, i havent read all the skully posts on the size of the board,but the NYC PARKS DEPT. used to paint these in yellow in most parks,has anyone checked with them,they may have old records on file. As i remember they all where the same size in the parks,they must have had a templete to make them all the same.I hope this helps.
