I found this the other day, and had some time to look it over. I added new seals. there is a flap on the collar above the valve that covers the air inlet. it was running a bit rough, so I blocked the air tube with my knife , and it brightened and smoothed out. so I bent the flap closer, and its much better. this light has a steel fount. I had thought these were brass founts, and all cracked. I have had a few of the 3705, but this is my first of this model. It needs more cleaning.
