1912 Buick Models

Hi, all

Can someone tell me what the various models were for Buick in 1912?

I know that Buick (General Motors) did not use model designations with
any logic or any consistency year-to-year, so it's hard for me to tell
what a particular car is.

There was a Model 28, 29, 34, 35, 36 and a model 43. Which was the
smallest? Which was the largest? I think some were Roadsters, others
Tourings.... Do you know the engine sizes? HP or bore and stroke?

Thanks very much,
