Missing Pages From Scott National Album For 1954-1965 Coil Definitives

For some reason my Scott National Album is missing two pages with the definitive coil stamps issued from 1954-1965 (stamp nos. 1054-1059, 1225 and 1229). One missing page has the single stamps and the other is for coil pairs. The attached image (taken from another collector's album for sale on ebay) shows the missing page for coil pairs. In my album, singles of coil stamps 1054-1059 are on the same page as definitive stamps 1043-1053. The page for the 1954-1965 [non-coil] definitives was updated so as not to include the coil stamps, but I didn't receive an update that has only the coil stamps (including stamps 1225 and 1229, the Jackson and Washington stamps issued in 1962-1963).
Does anyone have a suggestion for obtaining these two missing pages? I would obviously prefer not to have to purchase an entire new album!
Thank you!

This should be the missing image!

I wonder if the updated pages came in a supplement. I bought a 1978 Scott National back when that was the latest publication. I purchased supplements for many years. Then in 2019, I acquired a rather poorly maintained copy from the same era. I had also purchased the "recent" Part x pages that start in 1977(?) and overlap parts of my original album. I will look to see if I can find these pages. Perhaps I have multiple copies.
