1905 US race car: What is it?

I believe this to be Earl Kiser (Kaiser?), 1905, Harlem Racetrack Chicago. Don't know the occasion but what I really want to find out is - what's the car?
The third shot looks possibly to be the same car sans cowling, but have I been drinking too much or does it seem to have twin radiators? (ok .. heat exchangers).

Correction concerning Earl Kiser's track special:

It is not a Winton. The car is a 70-hp Tincher built in Chicago.

I couldn't find the exact bore/stroke dimensions. A 70-hp Tincher was exhibited at the Chicago show in February 1906, and described in "The Automobile" as "bringing back memories of Théry's 1904 Gordon Bennett winner".
Théry's Brasier engine displaced around 10 litres with the dimensions of 150/140 mm (the Brasier had cylinders cast in pairs, with L-head - the Tincher at the Harlem track had four single cylinders, with T-head).

This was posted the last time you asked about this car. Do you now believe Robert to be wrong, and if so, why?

... have I been drinking too much ...

I don't know but it seems something affects your short term memory.

This post of yours is just over two weeks old. Robert Dick answered twice.

EDIT: Tim Murray was faster.

And you're both obviously a lot sharper than I am. Genuine apologies for my altzheimer's episode.
Can either of you then perhaps shed light on the (apparent) twin radiators in the third image (I don't believe I have previously posted this in TNF..)
