Ah!
Found this photo. This is a "new" current manufacture Minilite wheel from GB that was supposed to be identical to the four magnesium wheels on my car. Well.. not quite. I ordered it in light alloy rather than magnesium. This car never came with a spare, or the hoop to hold it, just the spare platform brace, and bolt hole.
The "new" alloy had slightly more offset, the tapered seat insert for lug nuts, and the big problem, the inside edges of the webs did not clear the caliper for the front discs
. The whole wheel was made to exactly match the other four old magnesium Minilites, in about 30 minutes on the rotary table under a Bridgeport mill. An easy job.
