Diaphragm foil source

A friend of mine is experimenting with old tube condenser microphones. There had been numerous manufacturers in the early 50's. He found a no-name microphone which lets the foil tension to be adjusted, so there is no gluing involved. But the old aluminium foil was gone. He now uses he aluminium foil he took from a capacitor, which is approximately 0.005mm. This works, but the results are not that contenting. Are there manufacturers for these foils? He also would like to experiment with gold evaporated foils.
Thanks Ulrich Thielemann
