The Silhouettes have always had modular pickguard assemblies. Back then you could still order the Silhouettes in HSH, HH, HSS, and SSS configutions from the factory, plus you could order extra pickguard assemblies. They were (and still are) easily interchangeable, and it would not have been uncommon to change out the pickguard assembly to make a sale. Nothing wrong with that, as that was the purpose of the interchangeable pickguard assemblies.
