it is red dial literally, according to the picture attached. However the serial no. begin with 55 and the shutter speed likely belongs to a BD type, for instance a 1/30. Can you help me identify it? I care since I've heard a RD's shutter sound is lighter. Thanks in advance. $(KGrHqJ,!h!E9oZvvGFrBPonvBGFs!~~60_57 by GuoShuo, on Flickr

From the shutter speed of 1/30 and the 55xxxx number, it is almost certainly a BD from 1951. I'm not sure that the sound of the RD light weight shutter is much softer than a BD shutter in good condition, though.
