I am sorry I have upset you Gary. That was not my intention at all. I stumbled on this thread and saw the remark that the author of the font was unknown. As I knew who was the author I mentioned that and should have left it at that. But I didn't, sorry again.
The author info is not in the copyright line where it should (of course) be but in the version info line and that is, indeed, confusing.

On the Decodividers font/dingbat itself, yes, it is a quick and dirty crappy thing with crappy tracing from a crappy low resolution scan and it has numerous errors. Many less important but far too many that are important like contours with direction errors and intersecting coordinates and contours. I did see that you have dealt with quite a lot of those. The down-scaling, however, seems to have added other errors again.

Have fun
