How about the shoulders, would they be dropped? I did find one pattern. it is a 1958 pattern. I think the ribbed neck, bottom edge and wrists could be easily be left off. One nice thing is, is that the shoulder line is dropped. Or another words it extends past the shoulder line.
I found it at http://freevintageknitting.com/print/429
This pattern is from the 20th century and does not follow how a CW period sweater would have been made.
There are some ethnic examples of sweaters from the period, such as ganseys and the like. I have seen at least 3 CDVs of military-ish styled sack coat type sweaters and I am currently trying to work out a pattern for one. It is done in brioche stitch and is a cardigan.
