I don't have a definitive answer but I doubt it.
Propane quick-connects have only become popular standard options in the last 5-6 years. Before that I had only seen them on high end motorcoaches.
It would be fairly easy to add one. (they are low pressure and need the appropriate low pressure grill or a modification to remove the device's regulator)
An even easier way would be to add the high pressure adapter that screws in at the tank and allows the use of high pressure LP devices.
