I can't answer your suspension questions, but you can tell if it a 3 or 2 bearing by looking at the carb.side of the engine, in the crankcase towards the top and in the centre of the crankcase if there is a brass nut it's a 3 bearing.Mind you, you usually can tell a 3 bearing by the rumble from the centre main!.
As to your engine (crankcase) number M 188375 it dates to the end of December 1933 and is therefore a 2 bearing crank. Three bearing crank started at engine number 249052.
There's information on IFS (independent front suspension) systems on the Speedex site below - the first illustration of a red Bowden IFS with twin springs would appear similar to the set up you describe. The article includes a source for the Ford 10 track rod ends that yours may have.
