Hi Doug

I do, but I will probably need government clearance to obtain and forward the report….dates back to about 1995ish

It was used to determine the effects of lightning strike on avionics connectors and the customer was, I think, ITT Canon. How long have you got? From memory, there was no appreciable difference, but I cannot give you numbers. 

BTW, have you asked John Waryold - he remains the font of all knowledge….I have an email address for him if that might help?
