When I had my wire wheels rebuilt last year my car was up on jack-stands
for quite a while so I spent some time spline cleaning and got a really
close-up look at them.  My splines were definitely square-topped
triangles, thus:

         /   \ 

My wheels were manufactured by Dunlop, whom I assume built most of the
wire wheels used on British cars during this period.  Admittedly
my wheels were heftier than most, but I assume the design of the spline
shape was common.
