John, Jeff. FV623, and Dave, thanks for your help, I'm greatly obliged
, your info gives a lot of possible leads to run through Google.
I'm starting to consider other ways of trying to model this event, possibly have to leave some details un-distinguished, if others see this and think they'd like to do a similar display, I think that's a good thing.
Sure would be nice to see that photo Jeff!
Many thanks again!
Bruce
