Holden sidecars?

It was a sad day to hear about the planned closure of Holden in Australia. Following that announcement I read an article about the history of the company prior to being taken over by General Motors. In the early days of motoring most cars were imported as engines and rolling chassis and the bodies built here, much as trucks and buses are bought in still. Holden in South Australia was one of these and among other things they built motorcycle sidecars. I wonder if there are any still surviving and if anyone has a photo. Were they called Holden or something else? Mark Dodds Stanwell Tops, NSW
