Set N (metal version) - Two Fully Assembled Deluxe Goals.
"Manufactured in strong copper wire, with the posts and crossbars in lime acetate tubing and covered by real netting. Standard size"

The picture on the right shows the early goals (and balls) with the plain card boxes they were packed in. The metal goals do not have any lower support bars, but the metal makes them pretty sturdy. On the above set of goals, the nets have been fixed to the posts with black cotton.

These were the standard goals that were supplied in nearly every edition until the advent of the "New Type" and  "World Cup" Goals in the early 70's. They were still supplied with the Club Editions until the early 1990's. The early goals have brown nets, while later ones tend to have lime nets. A final variety came in a 1990's club edition and had red nets, but this was long after you could buy them as a separate item. They became C148 in the 1977 catalogue.
