I didn't have to hold and flip the undersides, the worker there (the manager) used their flashlight on the inside of the sleeves (Per Jonathan's request to me to know what lining he had used) and I also had looked under the lapels (which was leather) as there is a slight gap between the lapel and the leather.
I even asked questions about it and the manager said the people came in everyday to "service" the jacket (I forget the exact term he used) and that the jacket itself was stiff and fairly unwearable. That it was getting cracks and such in it.
The paint has really done a number on it over the years.
To be honest, I highly doubt he remembers even if we did ask. He has made 1000's maybe even 10,000's jackets over the years. I think he does over 50 movies, concerts, red carpet events, etc a year and produces a ton of products. He is the number one leatherworker in all of Hollywood and his time is in extremely high demand.
The things we do have from him are the original pattern and the muslin from Brad Pitt which is an exact copy and measurements of the jacket Brad Pitt wore. The muslin was what they used for the measurements to create the jacket.
