I am pretty sure of the dates and some of the details, but one thing that stands out was that Jerry Pilgram's yellow airplane with the flames was (is?) absolutely a magnificent model.
Frank McMillan and I were appearance judging at the 1974 Nats at Lake Charles (the first PAMPA Nats). (This is when models were inspected one-at-a time. The process to have all the models on the floor at the same time had not yet been invented.) That yellow airplane with the flames was brought to our table. It was amazing. The masking to do the multiple flames was flawless. We looked everywhere to find something wrong. I do not remember if those were the days of 40 appearance points, whatever they were, we gave that airplane maximum points.
That was 50 years ago and the that memory is still strong.
