It looks like I was right about the lens. Your lens should be a symmetrical convertible lens with 4 cemented elements per cell. About like a Protar VII.

Here are a few links to the Navy training books I mentioned:
Photographers Mate 3

Photographers Mate 3&2

Photographers Mate 3

Lots of variations, widely available from a variety of sources. Most I've seen are similar and should cover 4x5 Graphics, plus 8x10 view (loading, shooting, processing, and printing). Later ones may also feature Rollei and Lecia.

BTW, I believe George Tice trained as a Navy photographer (I should check that first, but think it is correct).
