Gents,
Actually, the lining was done with what we would call "Gut", a very thin lining of leather that was incompletely cured (Is that the right term Jerry?) and I have seen them with both red and blue accents. It is my understanding that the less than completely cured leather was used to ensure a complete/compatible fit.
I have a couple of originals FS/FT if anyone needs one.
