Thanks for the feedback.  I now have found the "Lead Demonstrator".  It
appears from the E-Mail I got that there are several devices to help skeet
and trapshooters learn proper lead.  The ones described in e-mail responses
to my querry sounded as if they were fixed on the end of the gun and not
adjustable.  The one I was trying to find is adjustable to teach the proper
lead for each station.  I found it at http://skeetandtrap.com

Thanks again
