Jim, The tree was NY 55140-9, a cross of Macoun and Purdue 54-12.  It
was offered in the 1970-1971 catalog, and described on pages 10 and 11. 
Ripens 8/24 at Geneva, "crisp, juicy, sprightly.  susceptible to rust,
resistant to mildew."  Uncle David's tree is grafted on M-7.  It is
about 12' high, and perhaps 20' across.  The shape could be described as
the top third of a sphere, with sturdy branches.

The tree is "trimmed" by deer to about 5" from the ground, fertilized by
same, but otherwise gets no care.  This year none of his apples cropped
- probably a combination of a large crop last year and lousy pollination
weather.  Usually, it has a few score of apples just ripening around
now, which makes it much more productive than the Macoun (usually only a
handful) or the other named variety (I forget, since it never has any
fruit), both on M106.  He also has two seedling trees selected from four
he transplanted from a footpath.  Both are huge and very productive. 
Neither has any apples to speak of this year, though.

I must report that the of the three apples I was able to find on the
tree, one had insect damage, and the other two were misshapen.  This is
unusual, and I expect is related to the cold wet summer.

p.s.  I don't suppose you sell the crab apple "Barbara Ann"?
