Ok found this one a little while ago, and am wondering if these stairs are to messed up to id whether it is a 38 or 40 reverse. Thanks Dave
Looks like Reverse of 1940 to me. You can tell because of the thicker top step (about twice as thick as the other steps), and the fact that the steps are so well-defined.
Thanks all, really appreciate it. Another day, and something new learned, so wasn't a total loss today after all. Dave
