[Rod.911S]

There's a small black & white picture of the box for the Canadian-made Webster air compressor (and the instruction sheet, the compressor unit, and the tool kit) on page 45 of the book "The 1974-1989 911 912E & 930 Porsche Authenticity Series" by Mark S. Habb (1995, Beeman Jorgensen, Inc.).

According to the book, an air bottle instead of the compressor was supplied for European cars. It seems that the compressor was stock for North American cars from 1974 when the collapsible spare was introduced (that spare first appeared with '73 non-US cars with the 85 litre tank). From '86, a German-made compressor, the Airmate 8000, was used.

I'll scan the photo tomorrow and post it.
