I am putting together an estimate that invloves removing and replacing wood siding. The house is approx. 200 years old so the existing siding also serves as the sheathing. I was planning on applying 15lb felt, then furring for a drainage plane and then install the new wood siding. My question is: would it be better to install wall sheathing (OSB or ridgid foam)? I will be installing only 175 sf of siding, but there is a chance the homeowner may want to do the whole house. Any comments are appreciated.

Have you had a chance to look hard at how the existing siding performed with the method that was used to construct the entire wall? How well does the current system perform with respect to insulation, etc?
Are you able to get similar or better quality siding to achieve the same wall strength?
I've seen very reputable folks repair/replace 100+ year old cedar roofing and siding using the same methods that were originally used (minus the paper insulation of course).
200 years of service has got to give some insight into structural and material performance that you can expect for the future and make the sale of your service experience based and prudent.
What type of wood siding is it? t&g?

Consider this, Dave. (I assume new windows will go in)
(1) If the walls have no corner bracing, from the exterior install 1x4 diagonal let in braces (or other such as metal T "Windbrake") at the corners or other wall locations.
(2) Add any recepatcles or newer services such as cable to each room that the customer may want. (the walls are open now)
(3) Air seal the back of the inner wall where necessary and install fiberglass batts -or- damp spray cellulose -or- spray light foam such as Icynene
(4) Install 1 or 1+1/2 inch rigid foam "sheathing" , then sealed exterior building membrane such as Typar/Tyvek.
(5) Install a rainscreen of 1x3 fastened through the foam to the studs
(6) Install windows and siding
Further to my last post:
The wood siding should be back primed with paint and all cut edges/joints should be painted.
