Yup. It's what was on it when I bought it. (The Lucas electronic probably gave way years ago and the PO went for a cheap fix.) The vacuum advance is kaput, and when I took it apart to check that the weights were free, they weren't standard for a 1275. I forget the specifics, but if the weights and springs were messed with, it was prob because the PO was playing with the curve for a 1500.
It runs, and doesn't ping with the advance set to 32 degrees at 3000 rpm. It's a little sluggish below 2K, which I'm sure is an advance issue. For now, it's good enough for me. One day I'll get around to it.
