Sock puppet,
Do you know in whose handwriting the Isaiah block portions that have survived were written in the O manuscript? I am wondering if perhaps they were written by someone other than the continuing scribe of the Book of Mormon and perhaps just inserted at a point and then 'translation' dictation resumed after that.
The Isaiah chapters in the “small plates” are:
1 Ne. 20 = Isa. 48
1 Ne. 21 = Isa. 49
2 Ne. 7 = Isa. 50
2 Ne. 8 = Isa. 51
2 Ne. 12-24 = Isa. 2-14
The scribes for the small plates are (gaps not indicated):
Oliver Cowdery = 1 Ne. 2:2-3:6
Scribe 2 = 1 Ne. 3:7-4:14
Oliver Cowdery = 1 Ne.4:15-20
Scribe 3 = 1 Ne. 4:20-12:8
Scribe 2 = 1 Ne. 12:9-16:1
Oliver Cowdery = 1 Ne. 16:1-Enos 1:14
I have adapted the above from Royal Skousen’s study. I think Joseph Smith treated this block as he did his so-called Inspired Translation of the Bible. He simply took a Bible and made corrections in it by “inspiration” and told Cowdery to copy it. This could be passed off as saving time. About this time, Joseph Smith and the Whitmers went to Palmyra to make arrangements with the printer, but for some reason Cowdery staid in Fayette. It’s possible he was copying from a marked Bible. If this is correct, then Whitmer would not have seen use of the Bible. In any case, he was responding to the claim the Spalding MS was the source for the Book of Mormon, which seemed impossible to him given what he had witnessed.
