Roger, but for your era, isn't the model with the high fans correct, I believe 64 came with those?
Ron, do you have any pictures of F3 #64 when it came onto the property? Which would have been F3 51A and later #101 because the original 64A was scrapped after Ash Grove?
F3 #64 also depends on which F3 of that number you are modeling.
But your F3's sure look good.....
