DAVE, Do not fall into the trap of waiting for a response, I understand this as my family does that ALSO, I AS YOU MIGHT GUESS DO NOT, IF A RESONABLE TIME GOES BY CONTACT AGAIN, AND AGAIN, BE A PIA SOMETIMES IT WORKS. Don
I love the research and creating projects for future builders, designers and 3D artists and the history of it all. Most of all it is the thrill of the hunt and the rush you get when you find it.
anyhow to a point you can push people for information but there is a point you get cut off and they no longer reply. Museums are great at this they will answer some basic questions but the more you ask the less you get. Perhaps it is the research fees they love to milk you out of.
