Joe, I have had good luck getting full size prints done at local Surveying firms. I also have used engineering firms, but surveyors tend to be smaller offices. The B&E print is what I am looking for since that is the tank I have. I would love to get the other one also, but I dont know about copying from tissue paper. What ever you can get copied and what ever price it ends up, I am game for it. Larry, the BT13 tank has never been previously approved so I suspect would be more difficult to deal with. I am also helping my I.A. try to get an undocumented tank approved in a Cruisair that he is doing an annual on. I help my I.A. and he helps me. It works out well that way. Joe, Thanks again. ____Grant.
