No, the 249 is the same as the 232 but with a larger meter.  I have 
both versions of the 232/249 manual, as well as a 232 in the flesh, 
and the 235 is obviously different.  It is said to have 25 Mohm DC 
input resistance rather than the usual 11 Mohm, and it has a 0.5v DC 
range.  The switch decks are considerably different from the 232.

So no, I'm pretty sure it is not the same as (or even very similar 
to) the 232/249, but rather is a significantly different design.

To anticipate another possible response: Yes, I know one on-line 
vendor claims to have manuals available, but I had a most unpleasant 
experience with them in the past and won't repeat that mistake.

So, back to the original question:  Does anyone have a manual (or at 
least a schematic) for the Model 235?
