Hello and thank you to everyone who responded to my post.  I am
no longer going to patch it, but I will attempt to re-cover the air
motor.  Now all I need to do is order parts.  I am glad that I was
persuaded to go the right route, as I think the patching would have
not worked.  The restorer was also very hesitant to recommend a
patching, and he too recommended re-covering the wind motor.

And, it looks like I have a three-point double pneumatic air motor.
Now I am off and running!

Very appreciative,
Erik York
