Hey Ming,
I bought one too, I got one without the twin stabilizers.
From what I was able to learn, the bows were made in the 70's in England for the English Olympic Archery Team.
How in the world C&B got them in the condition they are in is absolutely amazing. When I first saw them I thought they were old Hoyt target bows. The bow is gorgeous. The white/cream glass is perfect. The wood riser is outstanding. It makes a great form bow.
