For those interested, here is the 1773 map with this very odd shaped course, just as it was about to change with the advent of the Leger. The family name, incidentally, was pronounced Sallinger. This course was essentially by Rose Hill. There was a previous course near the present one before that.

Here is the OS 1st ed, with the course... the deaf and dumb institution is still there, or was the last time I went, one never knows nowadays...

Here is another way of portraying Merlin's excellent mapping, the OS confirming, if you can read it, that the other lines were training courses...

Here is the map, which I dated 1895, but this edition was done over a number of years... it shows a home straight too, which the photo yesterday seems to negate. JC regulations stipulated a straight of a mile by 1900 for most courses, but D was historic...

The notifications failed... I think I will just have to set up a general alarm at 12 pm on Monday... sitting at Newmarket selling books, a few anyway...
