Thanks to Paul for his feedback.But yesterday I was at the IPMS nats in Telford and bought the Precision Models 15cm sFH 18,what a stunning kit,anyway I was talking to the guy who researched and engineered these models,who told me that at least one of the cables is for braking the piece.As the gun was originally designed for being horse drawn,there was no method(time constraints I suppose) for hooking it up with air/hydraulics,so it was adapted by connecting the limber brake with a cable to the inside of the tractor.The brake was operated by a guy in the vehicle and not the driver.Hope this info will be of use to others.You learn something new everyday....regards to all,Dave.
