Yep. I remember sights. I think about half the folks I shot with in the late 50s early 60s used them. I tried them as well. Got quite accurate with them. I stopped using them long ago because they're not as quick or versatile as instinctive shooting. They don't work as well if one has to shoot from awkward positions, canting the bow, etc., and perhaps not as well on heavy bows which can't be held as long. However, on moderate weight bows, they do generally improve accuracy, or enable folks to attain a higher level of accuracy with less effort. I think we might see a little resurgence in their popularity.
Another, related observation from that era is that folks took much longer shots, both at game and on the practice range. A lot of field archery courses had 40 to 80 yard targets. They still do, I guess, but few traditional people shoot them nowadays. Maybe as our target shooting and hunting ranges became shorter there was less of a need for them.
