: : It didn't stand for anything, officially. The company was registered : as "SS Cars Ltd" with "SS" being part of the name itself, not an : abbreviation of the name.

But the cars made by SS Cars Ltd used engines from the Standard : Motor Company, so employees of Standard may well have been under the : impression that their comapny name formed part of the derivation (and : it's possible they were at least partly right). :
No they would not, that's like thinking the 'R' in TVR stands for 'Rover' because they use what most call the "Rover V8" (in fact a ex Buick design bought by Rover in the 1960s, hence why the P5 and P6 models in the Rover range were suffixed with a 'B' where the engine was fitted), as you say, "SS Cars" came into existence at the same time that the demise Swallow Sidecar company name cessed to be used so it's almost certain that the two are directly linked.
