Wonderful pictures Graham, thanks for posting. I love Edwardian and Vintage cars.
I've encountered that K-R-I-T a couple of times this year, most recently at Kop Hill - where sadly it also wasn't listed in the programme! I took this video of it at the Goodwood Breakfast Club in July:
I notice that it has two plugs per cylinder but only one is ever connected.
I don't know much about the company other than they were Detroit-based and made cars between 1909 and 1916. The company logo was a swastika before the symbol took on more sinister connotations.
