I RECENTLY PURCHASED A  1937 HART-PARR OLIVER 70 IN GOOD SHAPE, BUT IT NEEDS THE LARGE SIDE PANEL FOR THE RIGHT SIDE. THIS 70 HAS THE LOUVERS (VENTS) RUNNING VERTICAL ON THE PANEL. DOES ANYONE HAVE SUCH A THING THEY WOULD SELL OR IS THERE ANY REPRODUCTION PANELS AVAILABLE ANYWHERE??
                         THANKS,
                              CAL INNES
